WARNING!
Inpro produces unique modems which have no analogues. That is why it's not easy to find them and buy. There is so big demand for them that Inpro stopped assemblage of any models except IDC-2814 ones. These modems are based on the AT&T chipset and Russian microprogram.

OK
%C disables only MNP5 compression here, so it is preferable to turn it off. All other comands act accordingly to the AT&T command set. This modem likes hardware reset (&D3).

This modem has big differencies in S-registers to the previous, but command
set is mostly common.
Note: all the data about IDC modems here are related
to the Russian versions.
