Step 3: Install and Configure Your Software
You may use either the communication program included with your modem or a
third-party program. Communication programs designed for Windows 95/98/Me
and Windows NT/2000 normally do not need to be manually configured, since they
use the Plug and Play configuration supplied by the Windows modem driver. Com-
munication programs designed for DOS and other operating systems, however, may
need to be manually configured to work with your modem. Though each communi-
cation program is different, the following procedure should work with most of them.
1. Turn on your computer and run your communication program.
2. Find the dialog box or menu that lets you select your modem. (In Windows Ter-
minal 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 config-
uration 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 com-
mand, use ATZ. Note that the Z command must be in a command string by it-
self. 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 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.
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.
