PHONE connector.
9. Turn your computer on. Your modem is now
installed.
2.4 Hardware Configuration (Plug and Play)
Your modem is configured using the Plug and
Play (PnP) capabilities of your computer. Plug and
Play is a set of specifications that define the ability for
the computer hardware and operating system to auto-
matically configure all compliant devices that are in-
stalled, relieving the user of the need to determine
whichaddressesandinterruptstouseforeachdevice.
Consult your PC's owner's manual to determine if it is
PnP Revision 1.0a compliant. You most likely have a
Plug and Play Revision 1.0a compliant system if it was
purchased after June 1994 or if the BIOS is dated after
June 1994.
Proceed to one of the following sections, de-
pending on your system's configuration:
• Section 2.4.1 if you are running Windows
95 (with or without a Plug and Play PC)
• Section 2.4.2 if you are running Windows
3.1x or DOS on a PnP-compliant PC.
• Section 2.4.3 if you are running DOS or
Windows 3.1x on a non-PnP PC.
2.4.1 Configuring in Windows 95
The version of Windows 95 you have will deter-
mine which set of dialog boxes is presented to you
when installing the modem in Windows 95. Proceed to
one of the following sections, depending on your
Windows 95's diaglog box:

2.4.2 Configuring in a Plug and Play System with-
out Windows 95
When this modem is installed in a Plug and Play
system without Windows 95, the computer's BIOS will
assign a COM port and IRQ line to the modem.
Proceed to Section 2.5, Software Installation/
Configuration.
2.4.3 Configuring in a Non-Plug and Play System
ComputerswithoutnativePlugandPlaycapabili-
ties require the use of the included modem driver. If
you have not already installed this driver, refer to the
file README.1ST on the Windows 95 driver disk for
installation and configuration instructions. Once the
driver is installed the modem is enabled and config-
ured during system boot-up. The COM port and IRQ

Note that your software must be configured to
communicate with the modem on the same COM port
and IRQ line used by the modem.
2.6 Testing Your Modem After Installation
In order to test your modem you should be
familiar with your communication software. Load and
set up your communication software and enter into
“terminal mode.” Make sure that the COM Port and
IRQ settings of the modem match the software. Type
AT on your terminal screen and press ENTER. You
may see “AT”, “AATT” or nothing on the screen. In any
case, the modem should respond with an OK or 0. If it
does not, either the modem may not have been in-
stalled properly or the software has not been properly
configured. Review Sections 2.2-2.5 and be certain
that the modem and the software have been properly
installed. If required, refer to Section 6 for additional
troubleshooting information.
2.7 Using Your Modem
The communication software included with your
modem product provides a user friendly interface to
accessthefaxanddatafunctionsofyourmodem.This
software should be sufficient for all of your com-
munication needs. There may be times when you
need to access the modem manually via modem
commands. ReadSection3forasummarydescription
of the modem command set before manually access-
ing the modem. You may want to read the software
manual first, however, as the software may already
provide a user friendly method of accessing the func-
tions you need (i.e. dialing or answering calls).
2.8 Where To Go From Here
Youshouldfamiliarizeyourselfwiththefunctions
available from the included software by reading its
manual. You will be accessing most, if not all, of the
modem's functions from this software. You may also
use any other commercially available communication
software with the modem. Read Section 3 only if you
are interested in accessing the modem manually, and
not through the included software. Section 4 and 5

contain reference material, and can be skipped. If you
have difficulties getting your modem to work, read
Section 6 - Troubleshooting to find answers to com-
monly asked questions and problems.
Section Three - AT Command Set
3.1 Executing Commands
Commands are accepted by the modem while it
is in Command Mode. Your modem is automatically in
Command Mode until you dial a number and establish
a connection. Commands may be sent to your modem
from a PC running communication software or any
other terminal devices.
Your modem is capable of data communication
at rates of: 300, 1200, 2400, 4800, 9600, 14400,
19200, 28800, 38400, 57600, and 115200 bps. Make
sure your COM port baud rate settings in your commu-
nications software is set to one of the above speeds.
3.2 Command Structure
All commands sent to the modem must begin
with AT and end with ENTER. All commands may be
typed in either upper or lower case, but not mixed. To
make the command line more readable, spaces may
be inserted between commands. If you omit a param-
eter from a command that requires one, it is just like
specifying a parameter of 0. Example:
ATH [ENTER]
This command causes your modem to hang up.
3.3 Basic AT Commands

Section Four - S Registers
Your modem has 41 registers, designated S0
through S95. Table 4-1 shows the registers, their
functions, andtheirdefaultvalues. Someregisterscan
have their values changed by commands. If you use a
command to change a register value, the command
remainsineffectuntilyouturnofforresetyourmodem.
Your modem then reverts to the operating character-
istics specified in its non-volatile memory. Refer to
Section 3 for information on how to use the AT com-
mands to manipulate the S registers.

Section Six - Troubleshooting
This section describes some of the common
problemsyoumayencounterwhileusingyourmodem.
If you can not resolve your difficulty after reading this
chapter, contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the communication software is configured
to “talk” to the modem on the correct COM port and
IRQ setting (same COM port and IRQ setting as the
modem). Your communication software must know
which address your modem is using in the system in
order to pass data to it. Similarly, IRQ settings must
be set correctly to receive data from the modem.
2. Make sure that your modem is initialized correctly.
Your modem may have been initialized to not display
responses. You may factory-reset the modem by
issuing AT&F and press ENTER. The factory default
allows the modem to display responses after a com-
mand has been executed.
Modem does not dial.
1. Make sure the modem is connected to a working
phone line. Replace the modem with a working phone
to ensure that the phone line is working.
2. Make sure the phone line is connected to the jack
marked “LINE.” Incorrect connection prevents the
modem from operating properly. Refer to Section 2.3
for modem connection instructions.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the
modem and the software. Modem and software must
be configured identically.
2. Make sure the phone line is working properly. Re-
place the modem with a regular phone and dial the
number. If the line sounds noisy, you may have
difficulty connecting to the remote device.
Modem makes a connection but no data
appears on your screen.
1. Make sure the correct data format (data bits, stop bits,
and parity bits) and flow control (RTS/CTS) are being
15

used.
2. Make sure the correct terminal emulation mode is
being used (see communication software manual).
High pitch tone is heard whenever you
answer the phone.
1. Make sure Auto-Answer is turned off. Your modem is
factory configured to NOT auto-answer. Issue AT&F
to factory reset your modem.
Modem experiences errors while
communicating with a remote modem.
1. Make sure the DTE speed is the same as the modem
connection speed when in Direct Mode.
2. Make sure the remote system and your modem use
the same communication parameters (speed, parity,
etc.).
3. Make sure RTS/CTS hardware flow control is enabled
and XON/XOFF software flow control is disabled in
the communication software.
4. Make sure the data speed is not faster than your
computer's capability. Most IBM compatibles are
capable of 19,200 bps under DOS and Windows 3.X.
Operating at higher speeds under Windows requires
a 486 or faster CPU or Windows 95.
Modem experiences bursts of errors or
suddenly disconnects while communicating
with a remote modem.
1. Make sure Call Waiting is turned off.
2. Make sure the phone line does not exhibit excess
noise.
