4 Organizing and Configuring Your Modems

Configuration Planning
When configuring a MultiCommManager system, you may find it useful to ask yourself the
following questions.
Are your modems connected to one type of host device or to
multiple types of host devices?
The host device is the device that is connected to the serial port of the modem. Examples of
different types of host devices might be a UNIX system, an AS/400 system, a terminal server, a
remote node gateway, a fax server, etc. Different types of hosts can require different modem
configuration files and different Modem General Setup settings, because different hosts can
expect the modem to perform in different ways. It helps to put modems that are connected to the
same type of host in the same modem group, so the Configuration Options settings in the Edit
Modem Group dialog box can be set the same for the modems. Examples:
Host 1
A RASExpress server or a fax server needs no configuration because it reconfigures the modem
before and after every call.
Modem configuration file:
DEFAULT.CFG (not used)
Modem General Setup settings:
Asynchronous(default)
Dial-up (default)
None
Configuration Options settings for modem group Fax Server:
None (the fax server takes care of it).
Host 2
A UNIX system requires no responses from the modem unless given a command from the UNIX
system, and requires the serial port to be set to 19200 bps. Inbound security is required.
Modem configuration file:
Q2 (for quiet answer settings)
$SB19200 (for a serial port speed of 19200 bps)
Modem General Setup settings:
