Hi
I want to use a microcontroller(8051) that connected to modem(d-link) via rs232. when a ring signal come the micro must extract the caller ID (caller phon number) and if it was the particular one,reply to it and receive the data but if it wasn,t that number didn't reply to it.
So I am looking for pin out and the signalling procedure for the modem to do the mentioned project. Can any body help me?
thanks.
