Thanks for the reply, I tried calling after connecting it to the computer’s hyperterminal it works fine. But when I connect it to the Circuit, the LCD gives the message but the call isnt generated.
To check if the command is being generated from the MC, i had connected it to the hyperterminal, the codes I recieved in it were symbols and not the AT commands which was feeded in the C program.
Please could you help me with this difficulty,
Thanks
