Yes, it does.  The MNP Class available depends on the version of fimware
you have in your modem.

Version 4 firmware had support for MNP3 and parts of MNP4.
Version 5 and higher has support for MNP4 error correction and
MNP5 data compression.

You can find out the firmware in your modem by issuing the "ATI3" command.

You enable MNP error correction with the S95 register.  S95=2 is the
normal setting.  MNP5 data compression is enabled by setting S96=1.

MNP is only available in the slow speed modulations (2400 and 1200 bps).
PEP has its own error correction protocol, so it doesn't need MNP.

Done.
