    Accessing a PCI modem

    What I'm trying to do is talk to my PCI voice/fax modem using C. I need to be able to use the functionality of the modem to answer an incoming call, play a message, and receive DTMF (touch tone) signals. Is it possible to do this using C, or am I shooting to high here?

    For someone who knows C, and who knows how the device drivers are accessed on their operating system, it should be pretty easy.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I'm pretty sure that most standards modems don't know what to do with Dual Tone Multi-Frequecy (DTMF for anyone who doesn't know ).
