Wireless modules - help with code not working

[Dick Ivers]

Ioannis,
PIC to PC is working. Code and setup as follows:

The PIC echos back to the PC correctly. Double characters display as expected. Note that the transmission mode is inverted. I believe this mode is standard for RS232 communications. Also, I am using a null modem cable (Tx and Rx reversed ). I believe this is also standard. Haven't tried the radio link yet with this set up.. Any suggestions?

p.s. The DEFINES are capitals in the actual code. Not all show this way with the pasted code.
