Hi guys/girls
Anybody having problems communicating between their Mega and GM modem? My uC outputs the correct commands, and the modem works. However when connected TOGETHER they dnt seem to wrk. Modem jst not processing commands. I hv flow control switched off. I dnt need it here rite??
The GM-862 transmits on RxD and receives on TxD. That might be causing your problem.

Ive programmed my uC on an STK 500 and outputting with it…so youre saying I should try swopping the RxD and TxD lines???(will try it first thing tonight)
It sounds like you might have it wrong. Check the GM-862 hardware manual.
