You may use either the communication program included with your modem or a third-party program.
Communication programs designed for Windows 95 and above normally do not need to be manually
configured, since they obtain configuration information from Windows. Communication programs
designed for DOS and other operating systems, however, may need to be manually configured to
work with your modem. Though each communication program is different, the following procedure
should work with most of them.

1. Install and run your communication 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 PhoneTools select Configure | General Configuration | Communication | Change Modem.

3. Choose your modem from the program’s modem list. If it isn’t listed, choose a generic modem

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. 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 befor
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 that turns off autoanswer, type
AT&FS0=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.

7. 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.

8. If the program allows you to edit the no-connect messages (

NO CARRIER, BUSY, NO ANSWER,

NO DIALTONE), make sure there is no space between DIAL and TONE in NO DIALTONE.

9. Refer to the program manual or online help for other configuration choices. In most cases you can

accept the default values.
