Has anyone tried this?
What modem?
56k?
drivers?
success networking to a pc?
Make sure you don't get a winmodem. For them, all the guts of the modem are in (windows only) software. If you get a non-winmodem, it should act just like a com port. No drivers needed. Pick one on the linux hardware compatibility list. US Robotics is a good choice, although they made some winmodems also.
