This is *absolutely* false.  I type this while logged in using a pair of MNP 6
modems.  In fact, MNP 6 is a modulation scheme, not an error-control protocol.
I am fairly sure it's one of the many variants on v.29ft (or is that 27ft?) a
9600 bps main channel with a 300 bps backchannel.  File transfer performance
is about like the old HST protocol, which figures.  I am pretty sure MNP 8
exists.  I've also heard of MNP 10 being used in Microcom's specialized
cellmodems, but I don't have any confirmation for this.  Followup to
comp.dcom.modems.
