What about CR,LF?
Good point, i thought about that also, in c i made my serial port library with lots of fancy functions like putch() and putstr(), i got same result when i typed putstr("AT+CNMI=2,2,0,0,0n"); or when i typed putstr("AT+CNMI=2,2,0,0,0");
putch(10);
putch(13);
I even tried puting the command one char at a time with delay in between with same results.
Thanx
