modem communication

--------------------------------------------------------------------------------

hi all,

i want to test whether my modem is responding to the AT commands or not?

suppose if i send the command "at+crsm=?"
it will send me the response "OK"

my modem is connected to the PIC24F through UART interface..

can anyone tell me how to proceed further...

should i have to send AT command from the code

if i write
buf[] = " at + cmgs=?"

and send it
sendUART(buf);

and if i do
buf1[] = receiveUART();

will i get the response in buf1[] buffer

Thanks
Puneet
