Configuration Options settings for modem group UNIX:
On Disconnect (to make sure the modems are reconfigured after every call).
On Rack Power Up (to make sure the modems are reconfigured after the card is installed).

Are all the modems of the same type?
Modems are available for the MR4800 rack that meet two different standards: the MT1432MR, a
V.32bis modem with V.17 fax capabilities, and the MT2834MR/MR6, a V.34 modem with V.17 fax
capabilities. AT commands that apply to one of these may not apply to the other. For example, an
MT2834MR/MR6 can be set with a modem baud rate of 28,800 bps by the command $MB28800,
but the MT1432MR would give an error to this command. Because different modems may require
different configuration files, you may want to put all modems of one type into one modem group
and all modems of another type into another modem group.

Does the host system configure the modem?
Some host devices such as fax servers might initialize the modem before and after every call,
whereas other devices such as a terminal server might never configure the modem. If the host does
not configure the modem, then MultiCommManager probably should. If the host does configure
the modem, then MultiCommManager must not. If both the host and MultiCommManager try to
configure the modem at the same time, the host will error out because the modem ignores all input
from its serial port while the MultiCommManager is configuring the modem. Host systems that
configure the modem could be put into one modem group and host systems that don’t could be put
into another.
