Before You Begin your Installation
The product you have purchased is designed to be
easily installed into most IBM PC or compatible
systems. Many products have large, easy-to-read
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,
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 page.

product features and technical
questions (call 407-241-8088; M-F,
8 am to 6:30 pm EST). Direct
access to technical support
representatives is provided on a
limited basis.
If you require immediate attention
or in-depth help with the
installation of the product, please
call our 900-priority support number for service. This number gives
you immediate access to senior-level technicians. The number is 900-

Damaged or Missing Items
We use many world-class quality assurance programs to ensure the
product you purchased is of the highest caliber. Sometimes, however,
a component may be missing from the box, or is damaged or corrupt
in some way. If this happens, immediately return the entire package to
your place of purchase so you may exchange it for a new one. Your
dealer should be able to provide you with an exchange far more
quickly than by contacting us directly. If for some reason you are
unable to return the product directly to its place of purchase, refer to
the “Servicing Your Product” and “Warranty” sections in this manual
for instructions.

Using the Boca Research 14.4Kbps MODEM manual.
This manual provides installation and operating instructions for the
Boca 14.4Kbps MODEM. The manual assumes the user has basic
computer skills and is familiar with personal computers. Its primary
purpose is to provide physical installation instructions and basic
troubleshooting. All sections should be read carefully before
beginning any installation procedures. Our customer support
experience has shown that many costly and time-consuming calls to
our technical support staff can be avoided with closer attention to the
information provided here. In addition to following the instructions
provided in this manual, you will also need to consult the
documentation supplied with your communications software.
FCC Requirements
The Federal Communications Commission (FCC) restricts the way
you can use modems. Read the FCC compliance statement found in
Appendix D of this manual.
Connecting the Modem
You can connect the modem to various types of telephone jacks. The
acceptable phone jack types are RJ-11, RJ-12, RJ-13, RJ-41S, and RJ-
45S. Most homes and businesses use one of these jacks. If your
phone system does not have a modular jack, you can purchase an
adapter to convert your jack into an RJ-11C jack. Adapters may be
purchased from any local phone or electronics store.

a single device. It features V.32bis, which provides high-
speed data transmission plus support for V.42bis (error
correction) and MNP5 (data compression).
Features
• Data transmission rates of 14.4K, 12K, 9600, 7200, 4800,
2400, 1200, or 300bps.
• 100% data compatibility with the Hayes ‘AT’ command
set.
• Programmable speaker volume control
• Auto-speed sensing.
• V.32bis, V.42bis, and MNP5 are supported as well as V.42
and MNP 2-4 error correction, offering throughput speed
of 57,600 bps.
• Group III send and receive fax capability with support
for Class 1 and Class 2 fax commands.
• Supports 100 x 196 high resolution and 100 x 98 low
resolution.
• Communication ports selectable as COM1, 2, 3, or 4
using interrupts 3, 4, 5, or 7 (INTERNAL ONLY).
The Appendix features a discussion of standard and
extended ‘AT’ commands and S-Registers as well as high-
level protocols.
Introduction

14.4Kbps BOCAMODEM
Installation Hints
Your BOCAMODEM has been pre-set at the factory for
optimum performance. All defaults are set to allow the
modem to negotiate the best possible connection with
highest quality, data compression, and error correction.
Because of these factory defaults, the suggested
initialization (INIT) string is: ATZ.
If you want to custom configure your stored profiles, we
suggest that you always start out with an
AT&F&C1&D2&R1 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...&R1) to the modem.
Notes on Performance
To get optimum performance from your 14.4Kbps
BOCAMODEM, the phone line quality over which you
are transmitting and receiving must be reliable and
relatively free of “noise”.

2.2 Operational Requirements
The 14.4Kbps 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 14.4Kbps Modem with a computer
requires communication software, either as a stand-
alone product as included here, or as part of an
application program.
• The 14.4Kbps Modem takes a DB-25 (25-pin male
connector), but computer equipment varies. Check the
serial ports at the rear of your system.
• The 14.4Kbps 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 14.4Kbps Modem to
connect to your system’s serial port.

2.3 Connecting the Phone Line
An RJ-11 cable is provided with the purchase of your
14.4Kbps Modem. This section contains information you
will need before you connect the telephone line to the
14.4Kbps Modem and explains how to make the proper
connections from the 14.4Kbps Modem to your telephone
line.
Before you connect the telephone line to the 14.4Kbps
Modem, you should familiarize yourself, if you haven’t
done so already, with the information provided in the
Appendix of this manual concerning FCC and telephone
company requirements.

2.4 Preparing the Modem
Follow these simple steps to connect the modem to your
computer:
1. Turn off your computer and all peripheral devices.
2. Examine the back of the modem and review the
attached interfaces as shown above.

sections 2.6 Testing the Modem and 2.7 Testing the
Connection. Depending on the software you choose, refer
to the appropriate manual for start-up and configuration.
2.6 Testing the Modem
To verify that your modem is working properly, follow
these steps:
After making sure your communications software is
loaded and started, you are ready to test the modem’s
connection. Note the status indicators as explained on the
following page, then continue with 2.7.

2.7 Testing the Connection
1. 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 in 2.4 Preparing the Modem,
or refer to Troubleshooting (Section Four).
2. Your communications software should already be
loaded as instructed in 2.5. Most communications
programs when started are in command mode. Refer to
the program’s documentation for additional
information.
3. Type in the command ATZ followed by ENTER and the
14.4Kbps Modem will respond with OK. If the 14.4Kbps
Modem does not respond with OK, refer to the
Troubleshooting section of this manual.
4. 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.
5. Type ATH followed by ENTER to put the modem on
hook. This confirms that the 14.4Kbps Modem has been
successfully installed into the computer.
6. Your 14.4Kbps Modem is now ready for use. Continue
now with your communications software and
documentation.
