What baud rate and protocol does the modem need? You might be better using serout rather than debug.

I think You have to put off the echo off the modem

ATE0

-> OK

and don't forget to save it


AT&W
->OK

Thanks so much for your help,
I have solved the problem. What i think it was is that the DTR pin was floating. After i progrmmed the stamp i then grounded the dtr pin before the communication with the modem had begun. This solved the problem.
