What is IR-Transfer Utility C DLL?  
IR-Transfer Utility C DLL is a set of DLL programs which uploads and downloads program  
files, data files, or function files between the PDT 1100 and the host computer. This transfer  
is done according to the PDT 1100-IR protocol in the Windows 95 or Windows NT 3.51/4.0  
environment.  
Note: Uploading refers to the host's receiving files from the PDT 1100;  
downloading refers to transferring files from the host computer to the  
PDT 1100.)

DLL File Formats  
File Formats Supported by DLL  
The DLL supports user program files, function files, and date files.  
User Program Files  
Ir-Transfer Utility C DLL regards MS-DOS files with the extension .PD3 as user program files  
(object program files). Files are developed using the PDT 1100-BASIC 3.0 Compiler.  
As shown, each record in a user program file is fixed to 128 bytes in length (except the last  
record) and suffixed by a set of CR and LF codes (CR-LF codes), 0Dh and 0Ah.

PDT 1100 Terminal DLL Guide  
When downloading a program file, if the length of the last record is less than 128 bytes, the  
blank bytes (128 bytes minus last record length) are zero-filled so that every record is 128  
bytes long.

Note: In the PDT 1100-Ir protocol, CR-LF codes that are used as record  
separators in data are removed before file transmission.  
When receiving downloaded user programs, the PDT 1100 packs  
two-byte ASCII characters into two 4-bit hexadecimal codes in a  
single byte, to improve the PDT 1100s performance and memory  
availability.  
Function Files  
Ir-Transfer Utility C DLL regards files with the extension .FN3 or .EX3 as function files.  
These function files are contained in the PDT 1100-BASIC 3.0 Extension Library.

Note: In the PDT 1100-Ir protocol, CR-LF codes that are used as record  
separators in data are removed before file transmission.  
When receiving downloaded function files, the PDT 1100 packs two-  
byte ASCII characters into two 4-bit hexadecimal codes in a single  
byte, to improve the PDT 1100s performance and memory  
availability.  
Data Files  
Ir-Transfer Utility C DLL regards MS-DOS files with an extension other than .PD3, .FN3,  
and .EX3 as data files. Each record in a data file consists of one or more fields and suffixed  
by a set of CR and LF codes (CR-LF codes), 0Dh and 0Ah. An EOF (1Ah) code can be  
omitted.  
Data files can consist of ASCII text characters as well as arbitrary characters (00h to FFh).

To download data files, type the folder, file names, and the field lengths. Each field should be  
1 to 254 digits in length and the number of fields should be 1 to 16. The total field length  
(record length) plus the number of fields should be 255 or less.  
Designate field lengths in a file with the same file name but an .FLD extension as the file to  
download, in the directory where that file resides. When the data file is uploaded, Ir-Transfer  
Utility C DLL automatically creates the field definition file in the folder where the uploaded  
file is stored. For the .FLD file format, refer to Start of File Transmission on page 2-11.

DLL File Formats  
In downloading a data file, if the actual record length is less than the specified record length,  
the blank bytes are filled with space codes (20h); if it exceeds the specified record length, the  
excess is discarded.

Interpreting CR-LF Codes in records  
Ir-Transfer Utility C DLL interprets all characters 00h to FFh as data, but it usually interprets  
CR-LF codes in records as a record separator. If a record in a data file to be transmitted  
contains CR-LF codes, the Ir-Transfer Utility C DLL divides the record according to the  
record separator as follows.  
Specified Record Length  
Record n1  
CR LF  
Record n2  
CR LF  
When downloaded:  
Specified Record Length  
Record n1  
Record n2  
Space Codes  
Space Codes  
= Divided into two blocks  
during transmission

PDT 1100 Terminal DLL Guide  
To handle CR-LF codes as data, specify the +C option. CR-LF codes in records are  
transmitted as data:  
Specified Record Length  
Record n1  
CR LF  
Record n2  
CR LF  
When downloaded:  
Specified Record Length  
CR LF Record n2  
Record n1  
= Transmitted in a single block  
Even if you specify the +C option, use CR-LF codes as a record separator. If a records length  
is more or less than the specified record length in a file, an error (error code 76) occurs and  
the transmission is aborted. For the +C option, refer toOptions on page 2-7.  
To download data files containing CR-LF codes in records to the PDT 1100:  
1. At the host computer, specify the +C option in Ir-Transfer Utility C DLL  
2. At the PDT 1100, set the [Data] on the space code handling screen in System Mode  
(or in PDT 1100-BASIC 3.0, specify the T option to protocolspecin the XFILE  
statement) to regard space codes in the tail of a data field as data.  
If [Ignore] is selected (or no T option is specified), the PDT 1100 ignores space codes in the  
tail of a data field and data is not transferred correctly.  
For [Data] setting, refer to the PDT 1100 Product Reference Guide. For T option setting in  
the XFILEstatement, refer to the PDT 1100 Programmers Guide.

Directory Path Names and File Names  
Directory Path Names  
Specify the directory path of a file to be sent or received. You may specify either an absolute  
or relative path. If no path name is specified, the current working directory becomes active  
by default. Specification of a path name only is not allowed.  
Generally, no space code is allowed to be used in path names or file names; however, you can  
use space codes in path names by enclosing path names with double quotes as follows:  
c:\Program filesest.pd3”  
File Names  
Specify the name of a file to be sent or received. If you set the +R option for file reception and  
specified (file)as a file name, the host computer creates a receive file with the original file  
name used in the PDT 1100.  
Note: You cannot specify more than one file name in one function. To send  
or receive more than one file, add more than one line of the file  
transfer functions.

Select the PDT 1100-Ir protocol in the PDT 1100 when using Ir-Transfer Utility C and E DLL.  
The PDT 1100-Ir protocol automatically adds the serial number and horizontal parity, so  
other settings made in the PDT 1100 are ignored.  
To download data files to the PDT 1100 using +C option specified in the DLL, select [Data]  
on the Communications Protocol Option screen in System Mode to treat space codes in the  
tail of a data field as data. If you have selected the +C option, every record in a data file should  
be fixed in length (refer to Data Files on page 2-4) so that space codes used to fill blanks in  
the tail of a data field are data, not characters.  
Downloading  
Use the download menu in System Mode to download files. For details, refer to the PDT  
1100 Product Reference Guide.

The PDT 1100 System version 1.01 or earlier does not support setting the communications  
protocol type with the OUTstatement. Select the PDT 1100-Ir protocol in System Mode.  
Setting Communications Parameters using the OPEN “COM:”  
Statement  
You may set the communications parameters using the OPEN COM:statement. The following  
sample sets the optical interface and 115200 bps.  
OPENCOM1:115200AS#1  
Creating a Source Program Using the XFILE Statement  
You may develop a downloading or uploading source program that handles files according  
to the PDT 1100-Ir protocol using the XFILEstatement. Compile the source program into the  
user program and download it to the PDT 1100. For details, refer to theXFILEstatement in  
the PDT 1100 Programmers Guide.  
To download data files to the PDT 1100 using +C option specified in the DLL, specify the T  
option to the protocolspecof the XFILEstatement to treat space codes in the tail of a data  
field as data. If you have selected the +C option, every record in a data file must be fixed in  
length (refer to Data Files on page 2-4) so that space codes in the tail of a data field are data,  
not fill characters used to fill blanks in record when its actual length is shorter than the  
specified length.
