Configuring Your Software
You may use either the communication program included with your modem or a third-party program.
Communication programs designed for Windows normally do not need to be manually configured, since they
obtain configuration information from Windows. Though each communication program is different, the following
procedure should work with most of them.

1.
Turn on your computer and run your communications program.
2.
Find the dialog box or menu that lets you select your modem. (In Windows Terminal select
Settings | Modem Commands; in HyperTerminal select File | Properties | Phone
Number; and in the communications program select Configure | General Configuration |
Communication | Change Modem.

Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem
and modify the settings as necessary.
and modify the settings as necessary.
4.
Change the modem initialization string, if necessary. The factory default configuration works well
for most purposes. To load the factory default configuration, use AT&F. To load a custom
configuration that was saved using the &W command, use ATZ. Note that the Z command must
be in a command string by itself. For a Macintosh, the initialization string should include the
&D0 command. If you do not want the modem to always answer the phone, add S0=0 to the
string. To use Caller ID with the modem, add S0=2 to the string (Caller ID information is sent
between the first and second rings, so the phone must ring at least twice before the modem
picks up the line). Depending on the software, you might have to end the string with a carriage
return character (^M).

Note:
To change the modem’s default configuration, type new commands in the communication
program’s terminal window, adding the &W command to store them in the modem’s nonvolatile
memory. For instance, to create a default configuration for a Macintosh computer that turns off
autoanswer, type AT&F&D0S0=0&W. The new configuration loads automatically whenever
the modem is turned on or receives the ATZ command.

5.
Select the port the modem is connected to (normally COM1 or COM2).
6.
Select your serial port speed. This can be labeled “maximum speed,” “DTE bps,” or “baud rate.”
Ideally, if you use data compression, you should set your serial port baud rate to four times the
modem’s maximum transmission speed or faster; however, few files can be compressed
enough to require speeds that high, and not all serial ports can handle speeds that high.

If the communication program has an autobaud selection, make sure it is disabled. Autobaud
applies only to older modems, and can cause problems if enabled.

If the program allows you to edit the no-connect messages (NO CARRIER, BUSY, NO
ANSWER, NO DIAL TONE), make sure there is no space between DIAL and TONE in NO
DIAL TONE.

Configuring Your Modem
Your modem normally is configured through Windows or through the communication program you are using.
The default settings work best for most purposes. However, you also can configure your modem by sending
AT commands to the modem. See the AT Command Reference Guide for a list of AT (data) commands and
how to use them.
