  Well, if the USB "winmodem" is just a digital to analog/analog to
digital convertor with a USB interface, it shouldn't be difficult.  If you
the AD part samples the POTS line at 8000HZ with 8 bit samples, that is a
paltry 64Kbps.  

  I hope that winmodems aren't this profoundly stupid.  The
whole idea of offloading DSP functions to a general purpose CPU is
unappealing.
