WTI CMS-16; Console Management Switch -- User's Guide
1. Introduction
The CMS-16 Console Port Management Switch provides secure, in-band and/or out-of-band
access to RS232 console ports and maintenance ports on UNIX servers, routers and other
network equipment. System Administrators can access remote devices in order to change
configuration parameters, connect users to restricted ports, collect buffered data, and perform a
variety of other administrative functions.
Versatile Connectivity
Up to 16 different devices can be connected to the CMS without the need to select a common
baud rate or parity. Each port can be individually configured for specific baud rates, parity,
handshaking, and various other parameters and options.
Easy Set-Up and Operation
Configuration of the CMS is simple. A menuing system is used to select parameters, and enable
options. The CMS can easily adapt to the requirements of almost any data communications
application.
Limited Command Access
The CMS is ideal for situations that require limited access to important commands. Two
security levels allow each port to function as a Supervisor Port or User Port, depending on the
password entered at login. Supervisor Ports are allowed to change configuration, display status,
and connect to any other port; User ports are only allowed to connect to the ports provided by
their password. Each individual port can be assigned its own unique, user-defined password, up
to sixteen characters long.
Non-Volatile Memory
If AC power to the unit is lost or interrupted, the CMS's non-volatile memory will retain
user-defined parameters and port connections.
Modem and Telnet Communication
The CMS can be controlled by a local PC that communicates with the unit via cable, or
controlled remotely via external modem or telnet connection. Your terminal emulation or telnet
program is used to send commands to connect ports or display status.
Configuration Backup
Once you have configured the CMS to fit your application, parameters and options can be saved
to an ASCII text file on your PC. This allows you to quickly restore user-selected parameters if
the unit configuration is accidentally altered or deleted. Saved parameters can also be uploaded
to other CMS units. This allows rapid set-up when several units will be configured with identical
or similar parameters.
Typographic Conventions
Throughout this User's Guide, typefaces and characters are used to denote the following:
^
Indicates a control character. For example, the text "^X" (Control X)
indicates the [Ctrl] key and the [X] key must be pressed
simultaneously.

Figure 4.2: CMS Application Example (Not to Scale)
In this example, ports have been configured as follows:
● Network Port: The Network Port allows telnet access by remote Supervisors and/or
Users. When a telnet connection is established, the CMS will prompt the caller to enter a
password. If the Supervisor Password is entered, the CMS will recognize Supervisor Level
Commands; if a Port password is entered, the CMS will only recognize User Level
Commands. Supervisors are allowed to adjust port configuration, connect to any port, or
review unit status. Users are only permitted to review status and connect to ports that are
allowed by their Port password.
● Port 1 (System SetUp Port): This port has been left open in order to permit on-site
service personnel to access the Command Mode without disrupting other ports. Since
Port 1 is a System SetUp Port, the service tech is allowed password protected access to
Supervisor Level commands, and is able to connect to any port, change configuration, or
display unit status.
● Port 2 (Modem Port): An external modem has been installed at Port 2. This port has also
been configured for Modem Mode, which allows definition of a modem reset string,
initialization string, and hang-up string. When a caller contacts the CMS unit via modem,
a password prompt will be displayed. If the Supervisor Password is entered, the CMS will
permit access to Supervisor Level Commands; if a Port password is entered, the CMS will
only recognize User Level Commands. Supervisors are allowed to adjust port
configuration, connect to any port, or review unit status. Users are only allowed to review
status and connect to the ports allowed by their Port Password.

WTI CMS-16; Console Management Switch -- User's Guide
● Ports 5, 7, and 9 (User Ports): The Port Password "COLOCATION1" has been assigned
to these three ports. If the CMS is contacted via the Network Port or Modem Port, and this
password is entered at log in, Users will only be able to review status and connect to the
devices attached to Ports 5, 7, and 9.
● Ports 12, 14, and 16 (User Ports): The Port Password "COLOCATION2" has been
assigned to these three ports. If the CMS is contacted via the Network Port or Modem
Port, and this password is entered at log in, Users will only be able to review status and
connect to the devices attached to Ports 12, 14, and 16.
Note that in this example, Ports 3 through 16 could also be a mixture of ports connected to
external modems, and ports connected to devices such as file servers or archives. This would
allow remote users to dial in and access a specific file server or archive after entering a valid
Port Password at log in.
5. Configuration
5.1. Access to the CMS Command Mode
When the CMS Command Mode is active, commands can be invoked to select parameters, and
connect or disconnect ports.
Note: Command Mode cannot be accessed from a Buffer Mode Port, Passive
Mode Port, or any port that is currently connected to another CMS port.
1. Start your communications program (e.g. ProComm©). Make certain the CMS and
ProComm are set for the same parameters (e.g. baud, parity, etc.).
2. Access the Command Mode.
. Local Access: To access the command mode from a local PC that is connected to
the CMS via cable, press [Enter].
i. If you have already hit other keys, press [Enter] twice. There can be no other
characters preceding [Enter].
ii. If the Supervisor Password has been defined, the password prompt will be
displayed. Key in your Supervisor or Port password and press [Enter]. The
"CMS>" prompt will appear.
b. Modem Access: To access the command mode via modem, proceed as follows:
i. Dial the number for the external modem connected to the CMS.

ii. If you have defined the Supervisor Password, a prompt will be displayed.
Key in your Supervisor or Port password and press [Enter]. If the Supervisor
Password has not been defined, just press [Enter]. The "CMS>" prompt will
appear.
c. Network Access: In order to access the CMS command mode via network, the IP
Address, Subnet Mask and Gateway Address must first be defined. Therefore,
network access is not available during initial configuration.
may connect to the CMS via network using the following procedure:
i. Telnet to the CMS's IP Address. For example, if the IP Address is
"192.1.1.1", on a UNIX system, the Telnet command would be invoked as
follows:
$ telnet 192.1.1.1[Enter]
ii. Note that if the Telnet connection to the CMS is refused, this probably means
that the network port is busy, or that the IP Security feature has denied the
connection.
iii. If the Supervisor Password has been defined, the password prompt will be
displayed. Key in your Supervisor or Port password and press [Enter]. The
CMS will display the Port Status Screen, and then the "CMS>" prompt will
appear.
5.2. System SetUp Ports
SetUp Ports. Ports 1 and 2 will always permit password protected access to Supervisor Level
command functions, even when the unit is reset to default parameters.
In order to ensure that access to command functions is always available, Ports 1 and 2 cannot be
configured as Buffer Mode or Passive Mode Ports. Buffer and Passive Mode Ports are not able
to access the Command Mode. In addition, Ports 1 and 2 always permit password protected
access to Supervisor Level commands; the Supervisor Mode cannot be disabled at these two
ports.

(User) Passwords. The Supervisor Password allows system administrators to invoke unit
configuration commands, and the Port Passwords allow users to access specific ports in order to
create connections between ports or view port configuration parameters.
5.3.1. The Supervisor Password
The Supervisor Password allows access to higher level CMS configuration commands, which
administrators can employ to select communication parameters, set up IP Security, assign port
access rights, and perform other system management tasks.
When the Supervisor Password is defined (via the System Parameters menu), the CMS will
display a password prompt whenever you attempt to access the command mode. If the correct
Supervisor Password is entered, the CMS command mode then starts up in Supervisor Mode.
Note:
● If the Supervisor Password is not defined, then Supervisor Level commands
will be available to all ports, and port access and configuration functions will
not be password protected.
● If you wish to restrict user ports from changing CMS configuration
parameters or connecting to restricted ports, the Supervisor Password must be
defined.
● When the Supervisor Password is defined, the CMS will display a password
prompt when you attempt to access the command mode. Any RS232 port that
has not been assigned a Port Password, can then only be accessed using the
Supervisor Password.
Normally, the Supervisor Password can be entered at any port in order to gain access to
Supervisor Level commands. Note that if you wish to completely deny a port's access to
Supervisor Mode (even with the Supervisor Password), the Port Parameters menus (/P and /N)
can be used to disable the Supervisor Mode at ports 3 through 16 and the Network Port. The
Supervisor Mode cannot be disabled at System SetUp Ports 1 and 2.
Note that if the unit is reset to default parameters, all ports will revert to the default state, where
Supervisor Level commands are available to all ports, without password protection.
Note:
● When defining a Supervisor Password, it is strongly recommended that you
record the password for future use.
● If you forget or lose your Supervisor Password, you will not be able to access
Supervisor Level Commands. In this case, the only way to access the
Supervisor Mode, is to reinitialize the CMS to default values as described in

WTI CMS-16; Console Management Switch -- User's Guide
The Port Passwords (or User Passwords) allow system administrators to restrict access to a
specific group of ports. When the CMS command mode is accessed with a Port Password, users
may only connect to the RS232 Ports to which they have been granted access, and review
configuration parameters for those ports. Port Passwords do not grant access to CMS
configuration commands.
The configuration menus (/P) for each RS232 port allow a Port Password to be assigned to each
individual port. In order to allow a Port Password to grant access to a series of CMS ports, the
same Port Password is assigned to each port in the series.
For example, if the Port Password "test" is assigned to ports 3, 4, and 5, then when "test" is
entered at the Password Prompt, the user will only be able to connect to ports 3, 4, and 5, and
will only be able to view parameters for ports 3, 4, and 5.
If desired, all CMS ports can function as both a Supervisor Port and a User Port, depending on
which password is entered at the login prompt. However, if you wish to prevent a port from
being able to access the Supervisor Mode at all (even with the Supervisor Password), the
Supervisor Mode can be disabled at the RS232 Ports and the Network Port using the Port
cannot be disabled at Ports 1 and 2; these ports are designated as SetUp Ports, and are always
allowed password protected access to Supervisor Level commands.
5.4. Defining the Site ID and Supervisor Password
Before configuring individual ports, the Site ID and Supervisor Password should be defined. The
Site ID can be used to indicate the location or name of the CMS unit, and the Supervisor
Password is used to restrict access to sensitive command functions. Both the Site ID message
and Supervisor Password are defined via the System Parameters menu (/F).
Note:
● The Site ID cannot include double quotes.
● The Supervisor Password cannot include an asterisk, forward slash, spaces, or
double quotes.
● Both the Site ID and Supervisor Password will be cleared if the CMS is
initialized to default settings.
● The System Parameters Menu is only available in Supervisor Mode.
1. Access the Command Mode. When the "CMS>" prompt appears, type /F [Enter] to
display the System Parameters Menu.
2. Site ID Message: (Up to 32 characters; Default = undefined) Type 1and press [Enter],
the Site I.D. Prompt will appear. Key in the desired text and press [Enter] . To display the
Site I.D., type /J [Enter]. The Site ID is also listed on the Port Status and Port
Diagnostic Screens.
3. Supervisor Password: (Up to 32 characters; Default = undefined) Type 2and press

[Enter], a prompt will appear. Key in the desired password then press [Enter], the CMS
will prompt you to re-key the password in order to confirm spelling and capitalization.
Key in the password a second time, and then press [Enter].
Note:
● The Supervisor Password is case sensitive. Make certain to note the exact
password entered, including the case of each letter.
● Make certain to write down your Supervisor Password. If the password is lost
or forgotten, you will not be able to access Supervisor Level commands
unless you initialize the unit and clear all parameters as described in
5.5. Port Configuration
5.5.1. Configuration Conventions
When responding to prompts, invoking commands, and selecting items from the port
configuration menus, note the following:
● To select an item from a Port Configuration menu, key in the number for the item and
press [Enter].
● To clear an item in a Port Configuration menu, enter the number for the desired item and
press [Enter]. When the prompt appears, press [Space] and then press [Enter].
● When defining the Port Name, do not use the forward slash character (/), double quotes
("), the asterisk character (*), or blank spaces.
● Port Names cannot begin with a number.
● A Port cannot be named "N", this name is reserved for the Network Port.
● Refer to the instructions in each screen for additional functions available under that
screen.
● To exit a menu or prompt without changing its current value, press [Esc].
● Passwords and port names are case sensitive. When defining passwords and port names,
note the exact text, including the case of each character.
● The "Who" command (/W) can be used to display currently selected parameters for your
resident port. Note that when the Network port has been accessed using a Port Password
(User Mode), the /W command will only display the selected Logoff Character.

5.5.2. Port Modes
The CMS offers four different port operation modes; Any-to-Any Mode, Passive Mode, Buffer
Mode, and Modem Mode. The Port Modes function as follows:
● Any-to-Any Mode: Allows communication between connected ports. Any-to-Any Mode
Ports can be connected to other Any-to-Any Mode, Passive Mode, Buffer Mode, or
Modem Mode Ports by accessing Command Mode and invoking the /C command (see
● Passive Mode: Allows communication between connected ports, but does not allow
access to Command Mode. Passive Mode Ports can be connected by accessing Command
Mode from a free Any-to-Any or Modem Mode port and invoking the /C command (see
Section 7.1.1). The Passive Mode is not available to Ports 1 or 2 or the Network Port.
● Buffer Mode: Allows collection and storage of data received from connected devices.
Collected data can be retrieved by accessing Command Mode from a free Any-to-Any or
Modem Mode Port, and issuing the Connect (/C) Command. Note that the Buffer Mode
also allows pass-through communication with the connected device. The Buffer Mode is
not available to Ports 1 or 2 or the Network Port.
● Modem Mode: Allows communication between connected ports and simplifies
connection to an external modem. A port configured for the Modem Mode can perform all
functions normally available in Any-to-Any Mode. The Modem Mode also allows
definition of a Hang-Up String, Reset String, and Initialization String. Any CMS RS232
port can be configured for the Modem Mode. The Modem Mode is not available at the
Network Port.
5.5.3. RS232 Port Configuration Menus
The Port Configuration Menus are used to select options for each of the CMS RS232 ports.
Parameters selected via these menus will stay in effect until the unit is initialized or the /P
command is used to reconfigure the port. After initialization, parameters will revert to the
defaults specified by the Option Switches.
To select port parameters, proceed as follows:
1. Access the Command Mode. If the password prompt is displayed, key in your Supervisor
Level Password.
2. Type /P, followed by the number of the port to be configured, and press [Enter]. For
example, to configure Port 2, type /P 2 [Enter]. The Port Configuration menu will

❍ 73. Hang-Up String: Defines the modem hang-up message. Although the CMS
will pulse the DTR line in order to hang-up an attached modem, the Hang-Up string
is often useful for controlling modems that do not use the DTR line. (Default =
undefined).
● 8. Supervisor Mode: Permits or denies port access to Supervisor Mode. When this item
is enabled (Permit), and the valid Supervisor Password is entered, the port will be allowed
to invoke Supervisor Level commands. If this item is disabled (Deny), the port may not
enter Supervisor Mode, even when the Supervisor Password is entered. (Default =
Permit).
● 9. Logoff Character: Defines the Logoff Character for this port. The Logoff Character
determines the command sequence that must be issued at this port in order to disconnect
from a second port (Resident Disconnect). Note the following:
❍ The default Logoff Character is "+". As a result, the default Resident Disconnect
Sequence is [Enter]+++[Enter].
❍ The default three character Resident Disconnect Sequence uses the format
"[Enter]LLL[Enter]", where L is the Logoff Character. If the one character
disconnect is selected (see item 10), a resident connection is terminated by simply
typing the Logoff Character once (without carriage returns).
● 10. Sequence Disconnect: Enables/Disables and configures the Resident Disconnect
command. This prompt offers the option to either disable the Sequence Disconnect, select
a three character format, or select a one character format. (Default = Three Characters).
Note the following:
❍ When a Resident Connection is initiated, the CMS will send a message which lists
the connected ports, and displays the one character or three character disconnect
command that will be required in order to terminate the connection.
❍ The One Character Disconnect sequence is intended for situations where the
destination port should not receive the disconnect command. When the Three
Character format is selected, the disconnect sequence will pass through to the
destination port prior to breaking the connection.
❍ When the Three Character format is selected, the Resident Disconnect Sequence
will use the format "[Enter]LLL[Enter]", where L is the selected Logoff Character.
❍ When the One Character format is selected, resident connections are terminated by
entering the selected Logoff Character only. There is no need to press [Enter]
before and after the Logoff Character when the One Character format is selected.

● 11. Timeout Disconnect: Enables and selects the Timeout Period for this port. If
enabled, and the port does not receive or transmit data for the specified Timeout Period,
the port will disconnect. When the port is set for Any-to-Any Mode, Passive Mode, or
Buffer Mode, the default setting for this item is "OFF". When the port is set for Modem
Mode, the default setting for this item is 15 minutes.
● 12. Response Type: Selects the type of messages that this port will send in response to
commands. The user can select Verbose (English Text), Terse (Numeric / Abbreviation),
or Quiet Mode (No Response). (Default = Verbose).
● 13. Command Echo: Enables or Disables the command echo for this port. (Default =
On).
● 14. Accept Break: Determines whether the port will accept breaks received from the
attached device, and pass them along to a connected port. When enabled, breaks received
at this port will be passed to any port that this port is connected to, and sent along to the
device connected to the other port. When disabled, breaks will be refused at this port, and
hence, not sent to the other port. (Default = Yes)
5.5.4. Network Port Configuration Menu
In order to communicate with the CMS via network, the IP Address, Subnet Mask, and Gateway
Address must first be defined using the Network Parameters Menu. If desired, the Network
Parameters menu also allows you to implement IP Security features, which can restrict command
mode access based on the user's IP Address.
Settings for network parameters depend on the configuration of your individual network. Please

3. The IP Security Menu lists five IP Security "masks" along with the selected permit/deny
action for each mask.
. Each Security Mask prompt is used to define a specific IP address or range of IP
addresses. Each Mask Action prompt is used to select the permit/deny action for the
corresponding mask.
b. Masks are listed in order of ascending priority; Mask 1 has the lowest priority, and
Mask 5 has the highest priority.
c. Masks have a cumulative effect; high priority masks supersede the effect of lower
priority masks.
d. Each IP Address consists of a series of four eight bit numbers. The number 255 is
used as a wild card.
Example 1: Deny access to all hosts except 192.1.1.5:
● Security Mask #1: 255.255.255.255
● Mask #1 Action: Deny
● Security Mask #2: 192.1.1.5
● Mask #2 Action: Permit
Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants
access to 192.1.1.5 only.
Example 2: Allow access only by addresses that begin with 192:

● Mask #1 Action: Deny
● Security Mask #2: 192.255.255.255
● Mask #2 Action: Permit
Since 255 is a wild card, Mask #1 blocks all IP addresses Mask #2 then grants access to all
addresses that begin with 192.
Example 3: Allow access only by addresses that begin with 192, deny access to 192.1.1.5.
● Security Mask #1: 255.255.255.255
● Mask #1 Action: Deny
● Security Mask #2: 192.255.255.255
● Mask #2 Action: Permit
● Security Mask #3: 192.1.1.5
● Mask #3 Action: Deny
Since 255 is a wild card, Mask #1 blocks all IP addresses. Mask #2 then grants access to all
addresses that begin with 192. Finally, Mask #3 specifically blocks access by 192.1.1.5.
Note:
● Mask #5 has priority over the four other masks. If Mask #5 is set to deny
access by "255.255.255.255" (all wild cards), all IP addresses will be
blocked, and you will not be able to access the CMS Command Mode via
network. Access will only be allowed via the Console Port or Modem Port.
● When using the wild card address "255.255.255.255" to block access by all
IP addresses, make certain that at least one higher priority mask permits
access by your IP address.
5.6. Copying Parameters to All Ports
The /CP command (Copy Port Parameters) provides a convenient means for selecting identical
(or similar) parameters for all CMS RS-232 ports.
When the /CP command is invoked, the unit will display a menu which allows you to select port
communication parameters, and then copy them to all CMS RS-232 ports. The Copy Port
Parameters menu can be used to set all parameters for all RS-232 Ports, or define only a select
group of parameters and then copy them to all ports.
Note:
● The /CP command will not copy parameters to the Network Port.
● The /CP command is only available in Supervisor Mode.
● The Copy Port Parameters Menu will not display the Port Password. This
field will read either "undefined" or "defined", depending upon whether or
not the Port Password has been specified.
To select common parameters for all CMS RS-232 ports, proceed as follows:

be used to select only the Baud Rate for all ports.
Note: The /CP command will only copy the parameters that are currently
displayed by the Copy Port Parameters menu. Note that although the Port Password
is not displayed, the selected password will be copied if the field for this item reads
"defined".
4. Clear Menu: After defining several parameters, if you wish to clear the /CP menu and
start again, type -(dash) and press [Enter], the menu will be reset.
5. Copy Parameters: When you have finished selecting parameters, press [Esc] to copy the
selected parameters to all CMS RS-232 Ports and exit from the Copy Port Parameters
menu.

5.7. Save User Selected Parameters
Although this step is optional, it is strongly recommended to save all user- defined parameters to
an ASCII file. This will allow quick recovery in the event of accidental deletion or
parameters to an ASCII file.
6. The Status Screens
The CMS Status Screens display the connection status and communication parameters for the
sixteen RS-232 ports and the Network Port. There are four different types of status screens; The
Port Status Screen (/S), the Port Diagnostics Screen (/SD), the Network Status Screen (/SN), and
the Port Parameters Screens (/W).
6.1. The Port Status Screen (/S)
The Port Status Screen lists the general status of the CMS's
RS-232 ports. To display the Port Status Screen, access the command mode and type /S
Although both Supervisors and Users can display the Port Status Screen, the screen will appear
slightly different, depending upon whether the command mode was accessed with the Supervisor
Password or a Port Password. When a Port Password (User Mode) is entered at login, the Port
Status Screen will only display the status of those ports that share the same Port Password that
was entered at login.
When the Supervisor Mode is active, the Port Status Screen offers the option to either display or
suppress Port Passwords. Normally, when the /S command is invoked, the Password column will
read either "defined" or "undefined", depending upon whether or not the password for each port
has been specified. To display the Port Status Screen with Port Passwords included, type /SP
and then press [Enter]. Note that the /SP command option is not available in User Mode.

Note: When the command mode is accessed via the Network Port using a Port
(User) password, the /W command will only display the Sequence Disconnect,
Logoff Character, and the status of the Accept Break item.
7. Operation
7.1. Any-to-Any Mode
Any-to-Any Mode Ports can be connected to other Any-to-Any, Passive, Buffer, or Modem
Mode Ports by accessing Command Mode and issuing the /C Command. All ports can be
configured for the Any-to-Any Mode. Note that the Network Port is always configured for
Any-to-Any Mode.
7.1.1. Port Connection and Disconnection
The CMS provides communication between devices without the requirement that both devices
use the same communication parameters. This allows you to connect devices that use dissimilar
baud rates, parity, handshake, and etc.. The CMS converts data rates and other parameters,
eliminating the need to select common parameters for all connected devices.
7.1.1.1. Connecting Ports
Two different types of connections can be made between CMS ports; Resident Connections and
Third Party Connections.
● Resident Connections: Your resident port issues a /C command to connect to a second
port. For example, Port 4 issues the /C command to connect to Port 5.
● Third Party Connections: (Supervisor Mode Only) Your resident port issues a /C
command to create a connection between two other ports. For example, Port 1 is your
resident port, and Port 1 issues a command to connect Port 2 to Port 3.
Note:
● Third Party Connections can only be initiated from a port with Supervisor
Level command capability.
● The RS232 Ports cannot initiate a connection to the Network Port.
● If a port has accessed Command Mode using the Port Password (User Mode),
then that port will only be able to connect to other ports that share the same
port password.
To Connect ports, proceed as follows:
1. Access the Command Mode. If the Password Prompt is displayed, enter your Supervisor
or Port Password.

WTI CMS-16; Console Management Switch -- User's Guide
2. Invoke the /Ccommand to connect the desired ports.
. Resident Connect: To connect your resident port to another port, type /C xx
[Enter]. Where xxis the number or name of the port you want to connect. The
CMS will display the numbers of the connected ports, along with the command
sequence that will be required in order to disconnect the two ports.
Example: To connect your resident port to Port 8, type /C 8 [Enter].
b. Third Party Connect: (Supervisor Mode Only) To connect any two ports (other
than your resident port), type /C xx XX [Enter]. Where xx and XXare two port
names or numbers. The CMS will display the numbers of the two connected ports.
Example: To connect Port 5 to Port 6, invoke the following command at a port
with Supervisor Level command capability: /C 5 6 [Enter].
Note:
● Resident Connections: RS232 Ports are not allowed to initiate a Resident
Connection to the Network Port.
● Third Party Connections: RS232 Ports are not allowed to connect another
port to the network port. For example, Port 1 is not allowed to connect Port 3
to the Network Port.
When the /C command specifies the port name, it is only necessary to enter enough letters to
differentiate the desired port from other ports. Type an asterisk (*) to represent the remaining
characters in the port name. For example, to connect your resident port to a port named
"SALES", the connect command can be invoked as /C S*, providing no other port names begin
with the letter "S".
7.1.1.2. Disconnecting Ports
There are three different methods for disconnecting ports, the Resident Disconnect, the Third
Party Disconnect, and the No Activity Timeout. Providing the Timeout feature is enabled, a No
Activity Timeout will disconnect resident ports or third party ports.
Note: Option 74 in the Port Parameters Menu determines how the DTR signal will
react when the port disconnects. The DTR signal can either be held low, held high,
or pulsed and then held high.
1. Resident Disconnect: Disconnects your resident port from another port. For example, if
you are communicating via Port 3, and Port 3 is connected to Port 4, a Resident
Disconnect would be used to disassociate the two ports. The CMS offers two different
Resident Disconnect command formats; the Three Character Format and the One

. Three Characters (Default): Uses the format "[Enter]LLL[Enter]", where Lis
the selected Logoff Character. The Default Resident Disconnect Sequence is
[Enter]+++[Enter].
b. One Character: When the One Character Disconnect Sequence is selected, simply
enter the selected Logoff Character once (Default = +). Note that it is not necessary
to enter a carriage return before or after the Logoff Character.
c. If the default Resident Disconnect Sequence is not compatible with your
application, both the command format and Logoff Character can be redefined via
2. Third Party Disconnect: (Supervisor Mode Only) The /D command is issued from your
resident port to disconnect two third party ports. For example, if your Resident Port is
Port 1, a Third Party Disconnect would be used to disconnect Port 3 from Port 4.
. The /D command uses the format: /D xx XX[Enter], where xxand XX are the
numbers of the ports that you wish to disconnect, if an Nis entered, the command
will disconnect the Network Port.
b. The /D (Disconnect) command can only be invoked by a port with access to
Supervisor Level commands.
c. The /D command can specify both connected ports, or either of the two ports. For
example, if Port 1 is your resident port, any of the following commands can be used
to disconnect Port 3 from Port 4:
/D 3 4 [Enter]
or
/D 3 [Enter]
or
/D 4 [Enter]
3. No Activity Timeout: Providing the Timeout feature is enabled at either connected port,
the No Activity Timeout can disconnect Resident Ports, or Third Party Ports.
. RS232 Ports: To configure the Timeout Feature for the RS232 Ports, invoke the /P
command to display the Port Configuration Menu for the desired port as described
b. Network Port: To configure the Timeout Feature for the Network Port, invoke the
/N command to display the Network Port Configuration Menu as described in

WTI CMS-16; Console Management Switch -- User's Guide
Section 5.5.4. Option 15 enables and defines the Timeout Feature.
c. When the Timeout Feature is enabled, the port will automatically disconnect if no
data is received for the defined Timeout Period.
7.1.2. Defining Hunt Groups
A Hunt Group creates a situation where the CMS will scan a group of ports and connect to the
first available port in the group. Hunt Groups are created by assigning identical or similar names
to two or more ports. Hunt Groups can be defined using Any-to-Any, Passive, Buffer, or Modem
Mode Ports. Note that the Network Port cannot be included in Hunt Groups.
1. Access the Command Mode. If the password prompt is displayed, enter the Supervisor
Password.
2. Invoke the /P command to access the Port Configuration Menu for the desired Port(s) as
described in Section 5.5.3. For example, to configure Port 4, type /P 4 [Enter].
3. From the Port Configuration Menu, select item 1 to define the Port Name.
4. Repeat steps 2 and 3 above to assign identical names to the other ports in the Hunt Group.
For example, a series of ports in a group could all be named "SERVER".
5. To connect to the next available port in the hunt group, invoke the /C command using the
port name to specify the desired group. For example, /C SERVER [Enter].
6. Your port will be connected to the first available port in the group. If all ports are
presently connected, the CMS will respond with the "BUSY" message.
7. It is only necessary to enter enough letters of the port name to differentiate the Hunt
Group ports from other ports. Type an asterisk (*) to represent the remaining characters in
the port name. For example, to connect your resident port to the first available port in a
group of ports named "SALES1", "SALES2", and "SALES3", the connect command can
be invoked as /C S* [Enter], providing no other port names begin with the letter "S".
Hunt Group port names must be unique. Otherwise, ports with similar names will also be
included in the Hunt Group.
Hunt Group Example 1:
1. Ports 1 and 2 are Modem Mode ports, and modems are installed at both ports. Port 1 is
named "MODEM1" and Port 2 is named "MODEM2".
2. Your resident port is Port 4. To connect to the first available Modem, access the

Command Mode and type /C MODEM* [Enter].
Hunt Group Example 2:
1. Ports 3, 4, and 5 are Any-to-Any Mode ports. All three ports are named "SERVER".
2. Your resident port is Port 1, and you want to connect Port 2 to the first available server,
access the Command Mode and type /C 2 SERVER [Enter].
7.2. Passive Mode
Passive Mode Ports function the same as Any-to-Any Mode Ports, but do not allow access to
Command Mode. A Passive Mode Port can communicate with other ports, but cannot enter
Command Mode, and therefore cannot invoke commands to redefine port parameters, display
status, and etc.
Passive Mode Ports can be connected by accessing the Command Mode from a free Any-to-Any
Mode or Modem Mode Port, and invoking the Third Party Connect or Resident Connect
baud rate conversion.
Note:
● A Passive Mode Port is not allowed to access the Command Mode.
● In order to ensure supervisor access to important command functions, the
Passive Mode is not available to Ports 1 and 2 (SetUp Ports).
● The Passive Mode is not available at the Network Port.
7.3. Buffer Mode
Ports configured as Buffer Mode ports will collect data from the connected device and store it in
the CMS's statically allocated memory. Each CMS port features a fixed length, fixed position
data buffer.
The Buffer Mode allows collection of data from various devices without the requirement that all
devices use the same communication parameters (e.g. baud rate, parity, etc.).
Notes:
● Buffer Mode Ports cannot access the Command Mode.
● In order to ensure supervisor access to important command functions, the
Buffer Mode is not available to Ports 1 and 2 (SetUp Ports).
● The Buffer Mode is not available at the Network Port.

WTI CMS-16; Console Management Switch -- User's Guide
7.3.1. Reading Data from Buffer Mode Ports
To retrieve data from Buffer Mode Ports, you must first determine which port buffers contain
data. To check port buffers for stored data, access the Command Mode and type /S [Enter] to
display the Port Status Screen.
To retrieve data from buffer memory, go to a free Any-to-Any or Modem Mode Port, access the
Command Mode (Supervisor Level), and issue the /C command using the following format:
/C xx [Enter]
Where xxis the number or name of the port buffer to be read.
If the port's buffer is empty, the CMS will send a message which reads "Connected xx, Buffer
Empty"; where "xx" is the port number. If the buffer contains data, the CMS will display a
prompt that offers four options:
● Next Screen: To scroll through data one screen at a time, press the [Space] bar. Each
time the space bar is pressed, the next full screen of data will be sent.
● Scroll All: To send all data without pausing, press [1].
● Skip/Connect: To connect to the buffer port without sending stored data, press [2].
● Erase/Connect: To connect to the buffer port and erase stored data, press [3]. Note that
buffered data will be erased immediately and will not be sent.
Note: All four of these options also allow pass-through communication with the
device connected to the Buffer Mode port.
To clear data from the buffer, use the Erase/Connect option, or go to a free Any-to-Any or
Modem Mode Port with Supervisor Level command capability, and issue the /E (Erase Buffer)
command using the following format:
/E xx [Enter]
Where xxis the number or name of the port buffer to be cleared.
7.3.2. Port Buffers
The Status Screen lists the amount of Buffer Memory currently used by each port. The CMS
uses buffer memory in two different ways, depending on the user-selected port mode.
● Any-to-Any, Passive, and Modem Mode Ports: When two ports are communicating at
dissimilar baud rates, the buffer memory prevents data overflow at the slower port.
● Buffer Mode Ports: Stores data received from connected devices. The user issues a

connect command (/C) from an Any-to-Any Mode or Modem Mode port to retrieve data.
If the Status Screen indicates an accumulation of data, the /E (Erase Buffer) command can be
invoked to clear the buffer.
7.4. Modem Mode
In addition to allowing data transfer, the Modem Mode also provides additional functions
specifically related to modem communication. A Modem Mode Port can perform all functions
normally available in Any-to-Any Mode. The Modem Mode is available to all CMS ports except
the Network Port.
When the Modem Mode is selected, the port configuration menu (command /P) will display
three additional prompts, which allow the user to re-define the modem reset string, initialization
string, and hang-up string.
When the Modem Mode is selected for a port with Supervisor Level command access, the
Supervisor Password should be defined. This will discourage unauthorized access to higher
command functions.
When a call is received, the unit will prompt the caller to enter a password. The CMS allows
three attempts to enter a valid password. If the correct password is not entered in three attempts,
or if the user does not respond to the password prompt within 30 seconds, the modem will
disconnect.
The password can be defined and enabled by invoking the /P command as described in
Note:
● When a Modem Mode Port exits Command Mode, or the DCD line is lost
while the Command Mode is active, the CMS will pulse the DTR line to the
modem. The unit will then send the user-defined modem command strings to
make certain the modem is properly disconnected and reinitialized.
● When an external modem is installed at a CMS port, other ports can use the
modem for calling out. To call out, invoke the /C command to connect to the
port, and then access the modem as you normally would.
8. Saving and Restoring Configuration
Parameters
After the CMS has been properly configured, parameters can be downloaded and saved as an
ASCII text file. Later, if the configuration is accidentally altered, the file with the saved
parameters can be uploaded to automatically reconfigure the unit without the need to manually
assign each parameter.
Saved parameters can also be uploaded to other CMS units. This allows rapid set-up when

several units will be configured with the same parameters.
The "Save Parameters" procedure can be performed from any terminal emulation program (e.g.
ProComm, Crosstalk, Hyperterminal, etc.), that allows downloading of ASCII files.
8.1. Sending Parameters to a File
1. Start ProComm and access the CMS Command Mode. If the password prompt is
displayed, enter the Supervisor Password.

Screen to make certain the unit has been configured with the saved parameters.
9. Upgrading CMS Firmware
When new, improved versions of the CMS operating firmware become available, the "Upgrade
Firmware" function can be used to update the CMS unit. Updates can be uploaded via Setup
Ports One and Two, or via the Network Port.
Note: All other ports will be disabled during the firmware upgrade procedure.
1. Obtain the update file. Firmware modifications can either be mailed to the customer on a
3.5" diskette, or downloaded from WTI via modem. Place the diskette in your diskette
drive and/or copy the file to your hard drive.
2. Access the CMS command mode. If the password prompt is displayed, key in the
Supervisor Password. The Upgrade Firmware feature is only available in Supervisor
Mode.
3. When the CMS command prompt appears, type /UFand then press [Enter]. The CMS
will display a screen which offers the following options:
. Continue Upload and Keep Current Parameters: To proceed with the upgrade,
while retaining current, user-defined parameters, type 1and press [Enter]. All
parameter settings will be restored when the upgrade is complete.
b. Continue Upload and Default System: To proceed with the upgrade, and reset
parameters to default settings, type 2and press [Enter]. When the upgrade is
complete, all parameters will be set to default values.
Note: When the upgrade is performed via the Network Port, the CMS will not
default the IP Address, Subnet Mask, or Gateway Address. This allows the telnet
connection to be re-established after the upgrade procedure is complete.
c. Abort Upload: To cancel the upgrade and return to the command prompt, type 3
and press [Enter].
4. Use your communication program’s (e.g. ProComm’s) upload function to transfer the
upgrade firmware to the CMS unit. Select ASCII file format, and then specify the
filename and directory location where the firmware upgrade file resides.

5. If the upload is successful, the CMS will prompt the user to continue the upgrade or abort.
. Upgrade: To continue with the upgrade, type 1and press [Enter]. CMS will erase
the previous firmware, move new firmware from data flash to program flash
memory, calculate and store the new checksum, and reboot. Do not attempt to
reconnect to the CMS until the RDY indicator blinks to indicate the process is
complete.
b. Abort: To abort the procedure, type 2and
press [Enter].
6. Incomplete Upload: If the upload is interrupted, times-out, or if the file is corrupted
during transfer, the CMS will display a screen which asks for user confirmation before
proceeding. To proceed, type 1and press [Enter], then return to Step 4 above.
7. Emergency Recovery: In the rare event that the CMS operating system becomes
corrupted during installation, front panel indicators will blink five times and the unit will
automatically switch to Emergency Recovery Mode. Please contact WTI Customer
Service for further instructions.
When firmware upgrades are available, WTI will provide the necessary files via modem or
mailed diskette. At that time, an updated Users Guide or addendum will also be available.
10. Command Reference Guide
10.1. Command Conventions
The commands described in this section conform to the following conventions:
● Slash Character: Most CMS commands begin with the Slash Character (/).
● Apply Command to All Ports: When the asterisk character is entered as the argument of
the /Dcommand (Disconnect Port), or the /Ecommand (Erase Buffer) the command will
be applied to all ports. For example, to erase all port buffers, type /E * [Enter].
● Port Name Wild Card: It is not always necessary to enter the entire port name. Port
names can be abbreviated in command lines by entering the first character(s) of the name
followed by an asterisk (*). For example, a port named "SERVER" can be specified as
"S*". Note however, that this command would also be applied to any other port name that
begins with the letter "S".
● Suppress "Sure?" Prompt: When the /D(Disconnect Port), /E(Erase Buffer), or /I

(Default and Test Unit) commands are invoked, the /Yoption can be included in the
command line to override the "Are you Sure (y/n)?" prompt. For example, to disconnect
Port 8 without displaying the "Sure?" prompt, type /D/Y 8 [Enter].
● Enter Key: All commands are invoked by pressing [Enter].
● Command Mode: CMS Ports will only recognize commands when the Command Mode
has been activated. The Command Mode can be accessed from a free Any-to-Any or
● Connected Ports: When two ports are connected, most CMS commands will not be
recognized by either of the connected ports. The only exception is the Resident
Disconnect Sequence (Default = [Enter]+++[Enter]).
● Configuration Menus: To exit from a configuration menu, you must press [Esc] or
[Ctrl]+[X].
10.2. Command Response
When commands are sent to the CMS, the unit can respond with either verbose (English Text) or
terse messages (numeric / abbreviated). The default message type for all ports can be set to
either terse or verbose using Option Switch Six.
After the unit is installed and configured, the port configuration commands (/P and /N) can
specify an individual response format for each port. In addition to the Terse and Verbose
response modes, the port configuration commands can also select the Quiet Mode. When the
Quiet Mode is selected, the port will not send messages in response to commands.
The table below summarizes the various response messages for both the Terse and Verbose
modes.
