IrDA message selection from a menu

Eventually the primary will be a Palm and the secondary an ATmega128. 9600 baud.
During development the primary will be a PC. I would like a PC application where the user can select a message (e.g. XID) from a menu and send it. (I think this step-wise approach may be simpler than the 'big bang'.)
Using Codewright in hex I simulated an XID message:
unsigned char cFF3F[ ] =
0xFF, 0xC0, // typical XBOF, BOF
0xFF, 0x3F, 0x01, 0x00, // 00 - 03
0x00, 0x00, 0x00, 0xFF, // 04 - 07
0xFF, 0xFF, 0xFF, 0x00, // 08 - 11
0x00, 0x00, 0x00, 0x00, // 12 - 15
0x00, 0x00, 0x00, 0x00, // 16 - 19
0x00, 0x00, 0x00, 0x00, // 20 - 23
0x00, 0x00, 0x00, 0x00, // 24 - 27
0x00, 0x00, 0x00, 0x00, // 28 - 31
0x00, 0x00, 0x00, 0x00, // 32 - 35
0x7E, 0xF8, // 36 - 37 XCRC
0xC1, 0xFF // typical EOF, XBOF
Then, running Hyperterminal, I sent this as a text (i.e. not XMODEM, etc.) file. The application's state machine detects XBOFs, the BOF, the CRC, etc., and moves the data into the stack's buffer.
The next step is to replace the null modem cable with IR transceivers. (The PC's transceiver is a dongle.)
However I need an application that allows me to select a message (e.g. XID) from a menu and send it.
How can I do this?
