help with interfacing pic to GSM program

[mazemelb]

dear ederelk & goodgood,
i dont know if u set the proram to read from rs232. if u do, then u must have kbhit or anything similar to detect the incoming character frm rs232. then u must read from rs232 to extract the data from the modem. then u need to segregate the data or just extract the required data.

You need to match your baudrate. Problem will be resolved.

hello dera,
to communicate b/w microcontroler and GSM modem is quit simple..let me explain..
first connect your controller tx to modem Rx.then modem's Tx to hyperteminal or computer rx..and send AT commands..you will see if the controller is sending right data to the GSM modem..
its quit simple..do not to forget making common ground
