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.
