If you run into configuration difficulties with your communication software, it may be helpful to read the following section.

In setting up some older software programs, you may be asked to enter certain information. Most programs have default settings that are correct for use with this modem, and there is no need to change them. However, you should be aware of the following items:

If your fax software gives you the option of selecting Class 1 or Class 2 fax drivers, select Class 1.

Initialization strings and AT commands

An initialization string is a group of AT command settings that is sent to the modem as soon as you start up the software. The software determines which commands should be included in the initialization string, based on the device you select during installation. The commands remain in effect throughout the communications session, unless the software sends other commands to override them.

The software uses other AT command strings for all commands sent to the modem. This is transparent to you—the software does this in the background without you being aware of it.

It is sometimes necessary, however, to add other AT commands to initialization strings. You can find a table of AT commands on the
