i am trying a gsm communication through modem and microcontroller.
my aim is to send the command 'AT' and receive 'OK' or 'ERROR'.
my part of the code is
//
DB 'AT',0dh,0
; using zero(0) for end of the string
i am also using interrupt(i.e. when data from modem comes microcontroller will receive it and display it on LCD) .. but the problem is i am not getting response from modem .. means interrupt does not work ..
plz help ....
