First of all… thanks for your response sir.
As i tested the code with the hyperterminal…i could see the AT command printed on the terminal and as i press a key on the keyboard that gets printed on the lcd screan… so serial comm is of no problem.but when i interface pic with the gsm module. instead of getting OK i getback same command what i send(AT) on the lcd screan. suggestions pls.
