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. International
customers will find that contacting the place of purchase for
assistance will be much more efficient than contacting Boca
Reserach directly.
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. All phone numbers are based in the United States.

HOME/OFFICE MODEM
Installation Hints
Your HOME/OFFICE 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 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 before customizing other commands. This
string will reset the modem to the factory defaults as well
as reset some other basic settings.
Notes on Performance
To get optimum performance from your HOME/OFFICE
MODEM, the phone line quality over which you are
transmitting and receiving must be reliable and relatively
free of “noise”.

External Modem
Section Three: External Modem
Requirements and Status Indicators
The external version of the HOME/OFFICE 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:
nThe communication settings are controlled by the
software that manipulates the serial interface present in
your system. The external modem is connected to that
interface.
nOperating the HOME/OFFICE MODEM with a computer
requires communication software, either as a stand-alone
product as included here, or as part of an application
program.
nThe HOME/OFFICE MODEM takes a DB-25 (25-pin male
connector), but computer equipment varies. Check the
serial ports at the rear of your system.
nThe HOME/OFFICE MODEM uses an existing serial port (9-
or 25-pin connector) on the back panel of your computer.
You will need a 25-pin serial cable (available at most
computer retailers) to attach to the RS-232 serial port
connector on the back of the modem.
See the following page for a summary of the modem’s status
indicators.

Advanced Configuration
Section Four: Internal Modem: Advanced
Configuration for Windows 95
The Internal Boca Modem you have just purchased is an 8-
bit modem that can use IRQs 3, 4, 5, or 7. If you are
reading this section, it is probably because Windows 95
has already assigned all of the above-mentioned IRQs to
other devices in your system.
In order for you to complete installation of the modem,
you must first make one of the IRQs in the group 3, 4, 5,
and 7 available.
If you have an I/O card that may be using one of these
resources for an extra Printer Port, for example, you can
disable the extra printer port on the I/O card and make
that IRQ available for your new Home Office Modem.
Another option would be to change the IRQ setting on
any 16-bit device (e.g., sound card) you may be using.
These 16-bit devices may be using your system’s lower
IRQs, but are capable of addressing higher IRQs such as
IRQ9, 10, 11. For instructions on how to accomplish this,
please refer to the manual that came with your peripheral,
or call the technical support number for that product.
Explain that you are trying to change the IRQ setting on
your device in order to free up a resource for a modem.

HOME/OFFICE MODEM
Section Five: Troubleshooting
This section lists common problems that may be
encountered and their possible solutions.
nVerify that you have cables
plugged in correctly.
nConnect 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.
nCheck the connections between the
modem and the computer, and the
modem and the telephone line.
nMake sure the telephone jack is
operational as described above.
nThe telephone line may be in use
at a different extension.
nPerhaps the number you have
called does not reach a modem, or
the remote modem may not be set
up to respond.
nThere may be a conflicting port
address. Re-configure the modem’s
COM port address (INTERNAL
MODEL ONLY).
SYMPTOM POSSIBLE REMEDY
No dial tone.
Modem will not
connect to
another modem.
No response
when you type
in AT commands
HOMEOFF.PM6 5/9/97, 9:15 AM14

n Verify that the communication software
is set to the same communications port
where your modem is attached (e.g.,
COM1, COM2). Check IRQ settings in
your software and on the modem.
nCheck your serial cable connection
(EXTERNAL MODEL ONLY).
nTry typing AT&F to reset the modem
to its factory defaults.
nMove the modem to another serial
port (power down the host computer
first). If the modem works after being
moved, it’s likely the problem is not
with the modem.
nMake sure the echo command is set to
ON. Change to echo with the ATE1
command.
nMake sure the local (yours) and
remote modem configurations are
compatible.
nTurn off your modem (EXTERNAL),
exit, and re-run your communication
software.
nVerify that both modems are operating
with the same settings, speed, data,
parity, and stop bits.
nThe software may not be set for correct
terminal emulation. Configure software
to correct type. ANSI terminal
emulation is most commonly used.
SYMPTOM POSSIBLE REMEDY

SYMPTOM POSSIBLE REMEDY
nPower down your system
(INTERNAL) and re-run your
communications software. Check
software settings.
nExit the communications
program and restart it.
nYou may not have enabled auto-
answer. Use your software to
enable this function.
nIf you have an answering
machine, it may be answering

answering machine off, or, use the
software to set auto-answer to
respond in fewer rings than the
answering machine.
nCheck for any loose connections.
nRe-try the connection by dialing
the number several times. You
may be experiencing line
interference.
nAn incoming call may have
broken the connection if a call-
waiting feature was enabled.
Disable call-waiting and try again.

I am having trouble
getting my init
string to work.
Connection Errors
SYMPTOM POSSIBLE REMEDY
nInit strings are primarily
personal preferences. Use the
most basic one that can get the
job done. See Installation Hints
on page 8. An &Q6 (which
disables error control) is optional.
nTry connecting at a lower speed
(e.g., 9600 or 2400bps).
nTurn off error correction/
compression with an AT&Q6%C0
command.
nNoisy/poor line conditions may
prohibit connection. Have your
phone company test your lines.
nVerify that the modem at the
other end is up to date and
compliant with current CCITT
and Bell standards.

HOME/OFFICE MODEM
SYMPTOM POSSIBLE REMEDY
nSome on-line services require that
your modem be configured to run
with error correction and data
compression turned OFF. The
easiest way to accomplish this is by
using the command AT&Q6 and
setting the communication software
to the correct baud rate for the
service you are calling (e.g., 2400,
9600bps). If you still have problems
connecting, try forcing the modem
to connect up at the slower speed
with the commands
AT&Q6N0S37=6for 2400 baud, and
AT&Q6N0S37=9for 9600 baud
services.
nMake sure the AT&R1 is set in
your active profile.
