Re: modem to 8051 connection
in relation to my first querie..
we tried to test it first by connecting the µcontroller directly to the serial port of the PC(without using modem and telephone lines)it actually works..
then,we tried to connect two pc(hyperterminal)both have modems, using the telephone line inorder for us to test the connectivity of both modems..connecting pc to pc was quite easy. But since our project requires communication b/w pc and microcontroller,we find it very hard for the pc and the µcontroller to achieve handshaking,because we could not make the µcontroller to answer the call..what should we consider first in order to handshake?
