Hi,


        In one of my PIC projects, I am looking at connecting a PIC system
        via a modem to the standard phone line.

        My problem here is that my phone line is also used for voice.

        Is there a mechanism that can be built or that I could buy that
        would detect that it was not a modem and disconnect my PIC project,
        thus allowing me to talk to the person on the phone.

        I know I could get two phone lines, but I am looking at attempting
        to provide a system that could sit on the side and wait until
        I dial into the PIC system by modem.

        If there is such a product, would it work with phone lines in
        Australia.

Regards,


Robert.
