But in practice, it does work, and work well.   We have been using MNP modems
and e and f protocols for some time now for shipping news around, and have
yet to see a problem.   We run the computer<-->modem link at 9600 bps with
hardware flow control.  A 2400 bps modem<-->modem link can achieve throughputs
of up to 500 cps with MNP level 5.
