    I am trying to find a tutorial guide that explains how modem
    electronics work. So far without success.

    Have you come across a tutorial. If so, please post the URL

    If you need a tutorial on serial modem communications, a good place to
    start would be:

    That page is heavy on the general stuff and the cable pinouts, usually
    what you need first. Look at the links on the bottom of the page for
    more pages having to do with serial communications, and phone modems in

    As always, the Jedi master for serial communications tutorials for
    newbies is Jan Axelson of Lakeview Research, and the Book "Serial Port
    Complete" by that author. You can get it from libraries, Amazon, or
    the Lakeview Research website

    This webpage has links to everything. But if you really want to learn,
    try getting a hold of the book. It's great.

    Good luck

    If you could be more specific about your needs, you might get a better
    answer. I'm not really sure what you want.

    Good luck

    Sounds like he wants a description of how they shove 56,000 bits per
    second of data through a POTS line that's only guaranteed to 3 KHz.

    Good Luck!

    I am looking for how the electronic components on the PCB process the
    electrical signals to give information ( and how the components work

    Thanks again
