Hi, I am using 8051 to control teh GSM module. Both are working fine with the terminal commands. But when I send the same command from the controlle rto modem, modem is not responding. i iwant the information from teh modem. so first I send the command and then I activated the serial interrupt to recive the data from the modem. Some where I am missing it out. Can somebody help me in thsi regard.thank you
There are very many things that can stop serial comms from working:
Software - including configurations of baud rate, parity, control signals, etc; Electronic hardware - including the RS232 transceiver; Other hardware - cables, etc.
You need to ensure that they are all correct & working!
