legends to allow for the easy configuring of the
product. This installation manual contains detailed
instructions. Most included software has automatic
installation programs to place the software correctly onto your
computer. However, as all computers are configured differently, you
may be required to perform some basic DOS or Windows tasks. If you
are not familiar with basic DOS commands such as DIR, CD, or EDIT,
3
you should check your DOS manual, or seek assistance from you local
computer dealer to install the product.
How to get Technical Assistance
The dealer that you purchased this product or your computer from is
the first place you should go for technical assistance. The dealer is
usually the most qualified source of help, and
is most familiar with your system and how
this product should be installed. Many dealers
have customer service and technical support
programs, with varying levels of support offered, depending on your
needs and computer knowledge. Please contact the dealer first
whenever a problem occurs.
If your Dealer Can’t Assist you
If you can’t get assistance from your dealer, the manufacturer provides
varying levels of technical assistance as summarized on the following

2. If you are using a telephone, check for a dial tone
using the telephone handset. If a dial tone is heard,
continue with the next step. If you do not hear a dial
tone, check the connections you made on pages 8-10,
or refer to Troubleshooting (Section Three).
3. Your communications software should already be
loaded as instructed on page 10. If not, start it now
and enter terminal mode.
IMPORTANT: If you are not in terminal mode and you type
AT commands at the DOS prompt, a “Bad Command or File
Name” message will result.
4. Type in the command ATZ followed by ENTER and
the modem will respond with OK. If the modem does
not respond with OK, refer to the Troubleshooting
section of this manual.
5. Start your communications software and enter
terminal mode; AT commands typed in at the DOS
prompt will result in a “Bad command or file name”
message. Type ATH1 followed by ENTER and you
should hear a dial tone from the speaker on the
modem.
6. Type ATH followed by ENTER to put the modem on
hook. This confirms that the modem has been
successfully installed into the computer.

Product Overview
14
The Appendix features a discussion of standard and
extended ‘AT’ commands and S-Registers as well as
high-level protocols.
Installation Hints
Your modem has been pre-set at the factory for
optimum performance. All defaults are set to allow
the modem to negotiate the best possible connection.
Because of these factory defaults, the suggested
initialization (INIT) string is: ATZ. You should change
the INIT string in all of your software packages to this
INIT string.
If you want to custom configure your stored profiles,
we suggest that you always start out with an
AT&F&C1&D2 before customizing other commands.
This string will reset the modem to the factory
defaults as well as reset some other basic settings. If
modem performance suffers after modifying settings,
send the INIT string above (AT&F...&D2) to the
modem.
Notes on Performance
To get optimum performance from your modem, the
phone line quality over which you are transmitting
and receiving must be reliable and relatively free of
“noise”.

Operational Requirements
The modem has few requirements and is easy to use.
Be sure to read the information in the Appendix about
connecting to the phone company. In addition, note
the following:
• The communication settings are controlled by the
software that manipulates the serial interface
present in your system. The external modem is
connected to that interface.
• Operating the modem with a computer requires
communication software, either as a stand-alone
product as included here, or as part of an
application program.
• The modem takes a DB-25 (25-pin male connector),
but computer equipment varies. Check the serial
ports at the rear of your system.
• The modem uses an existing serial port on the back
panel of your computer. It can be a 9-pin or 25-pin
D-shell connector. Use the dual end (25-pin or 9-pin)
of the cable supplied with your modem to connect
to your system’s serial port.

Section Three: Troubleshooting
This section lists common problems that may be
encountered and their possible solutions.
SYMPTOM POSSIBLE REMEDY
No dial tone.
Modem will not
connect to
another modem.
• Verify that you have cables plugged in
correctly as instructed in Section Two.
• Connect a telephone set directly to the
wall jack and check for a dial tone. If
no dial tone is heard, the telephone line
is not working. Contact the telephone
company.
• Check the connections between the
modem and the computer, and the
modem and the telephone line.
• Make sure the telephone jack is
operational as described above.
• The telephone line may be in use at a
different extension.
No response
when you type in
AT commands
On-Line EXPRESS
• Perhaps the number you have called
does not reach a modem, or the remote
modem may not be set up to respond.
• There may be a conflicting port
address. Re-configure the modem’s
COM port address.
