Subject: MNP level 4 to MNP level 5

I am using an EMEX 2400EC modem which supports MNP level 4.
Whenever I call to an HST modem with MNP level 5 I cannot
connect with error correction (MNP).  It is my belief that when
2 modems that support MNP are attempting to connect, they should
step down until they reach a level of MNP that is supported by
both modems.

I can connect to PC-Pursuit with MNP error correction and they
only support up to level 3.  I can also cause PC-P's outdial
modems connect to an HST (MNP level 5) modem.  I just cannot
make my modem connect directly with an HST (level 5).  Any
suggestions?

MNP, up to level 4, is supposed to useful in using modems over
dirty phone lines.  Sometimes my line get quite noisy and it
would be useful to be able to use this feature.  Thanks in
advance.

NOTE: The modem is manufactured by INCOMM DATA SYSTEMS, INC. and
I'm using it on a TeleVideo TS803H CP/M system.
