Serial/Telnet Command
Overview
BWS-136 provides a set of ASCII command to configure Aport
through a serial and Ethernet port. User can use serial terminal or
Telnet command to configure BWS-136 when Web browser and
Java utility are available. In addition, these functions provide
user the most convenient way to develop their own configuration
utility software simply to use the ASCII command.
Serial Console Mode
To enter the Serial console mode, you can switch SW1 (4~5) to
ON position and then serial port will function as a console port.
The READY LED will keep flash that indicates BWS-136 is in
serial console mode. Please set the serial data setting of the Serial
Terminal software (such as Hyper Terminal) to be the same as the
BWS-136 serial port. If you forgot the serial port setting, you can
use SW1 to reset it to factory default setting as use following
setting:
Baud rate: 19200
Data Format: N,8,1 ( Parity, Data bits, Stop bits)

Flow Control: None
Forgot Password
Interface: RS-232
Now you can use serial terminal software to send the ASCII
command to BWS-136.
If you forgot the Password, you can switch SW1 to Factory Default
setting mode and use default IP Address 192.168.16.10 and enter the
Web console pages. Once the configuration is completed,
remember to switch SW1 back to Normal operation mode and
reboot the module by Reset Command or push reset button.
Password is not required for serial console mode. Therefore you
can also use serial console to reset the password.
In Serial Console Mode, all the network functions will be
disabled
Once the configuration is completed, remember to switch SW1
back to Normal operation mode and reboot the module by Reset
Command or push reset button.
Command Syntax
The command syntax is
Telnet Console Mode
[Delimiter][Command][Carriage Return/CR][Line Feed/LF]
Delimiter (one byte): The command begins with a delimiter of
dollar sign $ and if BWS-136 receives the correct command it will
response with an echo which begins with the delimiter of a
percentage sign %.
BWS-136 uses Port number 5001 as telnet console port.
Remember to turn on the LOCALECHO before opening the telnet
console port. You must login first before sending command to
BWS-136. If password is enabled, you need to use the password
to log in. The password is encrypted using Tiny Encryption
Algorithm (TEA) and the keys are sixteen bytes with low case
character from “a” to “p”. The login command format is as
follow:
Command: The command are ASCII string which contains three
elements: {Read/Write}{Function}{Parameter} as described as
follow:
$LOG[16 bytes of TEA Encrypted Password]
or
$LOG
if there are no password settings

Echo Syntax
Appendix A
After BWS-136 console port received correct command string, it
will response Echo String and the Echo Syntax is as follow:
[Delimiter][Function][Status]
Tiny Encryption Algorithm
Delimiter (One byte): A percentage sign “%”
Function (Two bytes): function string
1. Example of TEA.C
/************************************************
Status: “OK” or “FAIL”
The Tiny Encryption Algorithm (TEA) by David Wheeler and Roger Needham of the
Cambridge Computer Laboratory. Placed in the Public Domain by
David Wheeler and Roger Needham.
For example: Set the IP Address by sending command
$SLI192.168.16.100(CR)(LF)
**** ANSI C VERSION (New Variant) ****
Echo string
Notes:TEA is a Feistel cipher with XOR and addition as the non-linear mixing
functions.
%SLIOK(CR)(LF)
means the new IP address is successfully transferred to the module
and the new setting will be effective after reboot the module.
To get IP address setting, you can send a command as follow
$GLI
Takes 64 bits of data in v[0] and v[1]. Returns 64 bits of data in w[0] and w[1].
Takes 128 bits of key in k[0] - k[3].
TEA can be operated in any of the modes of DES. Cipher Block Chaining is, for
example, simple to implement. n is the number of iterations. 32 is ample,
16 is sufficient, as few as eight may be OK. The algorithm achieves good
dispersion after six iterations. The iteration count can be made variable if
required.
then the Echo string will be
%GLI192.168.16.100
Always remember to reboot the module by send command
Note this is optimised for 32-bit CPUs with fast shift capabilities. It can very
easily be ported to assembly language on most CPUs. delta is chosen to be the
real part of (the golden ratio Sqrt(5/4) - 1/2 ~ 0.618034 multiplied by 2^32).
This version has been amended to foil two weaknesses identified by David A.
Wagner ([email protected]): 1) effective key length of old-variant TEA was
126 not 128 bits 2) a related key attack was possible
