I’m trying to send some data from an electric meter trough GPRS connection. I have a PIC microcontroller between the electric meter and the Wismo 2406B GSM/GPRS module, but I can stablished the connection. I try to connect the 2406B module to the PC and work with the hyperterminal, but when I send ATD99**1# I have some garbage in the screen and after a few second the NO CARRIER message appears on the screen.

thanks in advance for your help

best regards


This garbage are PPP frames.
