There is more to WinModems than this. According to your definition
there must not be any WinModems for NT alas there are some.
At least the Lucent PnP WinModem (which I have in my Acer Notebook)
uses a DSP to do all the hard work and the onboard CPU just for
non-timecritical things like the V.42 protocol. It should be possible
to write a driver for such a modem and use the existing code for sync
serial communication as a base for the CPU stuff (Don't ask me to do
this... ;-) )
So there is more than one truth.

This is not correct. You can get documentation for the Lucent chips
from www.lucent.com.

I have a notebook with onboard modem. What should I do, rip it out?
Kind regards
