I too was under this impression, but my Octocomm OSI8224A MNP4 modem
always seems to play up when connecting to non-MNP modems. Most frequently
I get every character that the remote system sends preceeded with a "?".

Also, I have had another problem with the MNP 4 emulation in the Octocom.
When I connected to an MNP 5 modem, our throughput with an error free
Z-Modem transmission was only 113 CPS, whereas if I turn off my error
correcting (MNP), I get 236 CPS.

Any suggestions as to what I might be doing wrong, or is MNP 4 not all that
it is cracked up to be ?
