I'm able to send AT commands to GSM modem,
but i am not able interface my 8051 to GSM model.
can i get sample inerfacing code for 8051 micro controller.
I have no beef whatsoever with "testing" I do it all the time.
What I have a beef with is that "it worked" qualifies as "testing" and a guarantee that everything is correct.
succesful testing does not prove the abscence of bugs, it ONLY proves the abscence of KNOWN bugs
