Serial Modem communication.

Hi ,

I am trying to send data from my micro-controller to PC.
I am able to detect incoming ring pick up the modem and send data. The Data that i am sending is received by the PC but If i send some thing from the PC i do not receive it at my controller my problem is i have only a single Pin available. so can i do some thing so that i am able to receive data?

Thank You

    "I am able to detect incoming ring pick up the modem and send data."

    Is that at the microcontroller end, or the PC end?

    "my problem is i have only a single Pin available"

    Surely, to use a modem you must be able to both send commands to it and receive responses from it. How are you doing that with only a single pin??
