Introduction
How a Modem Works
A modem is a computer peripheral that allows you to
communicate with other computers via telephone lines. Because
ordinary telephone lines cannot carry digital information, a
modem changes the digital data from your computer into analog
signals, which can be transmitted much like voice signals. In a
similar manner, the modem receiving the call then changes the
analog signals back into digital data that the receiving computer
can understand. This shift of digital data into analog signals and
back again allows two computers to “speak” with one another.
Called modulation/demodulation , this transformation of data and
signals is how the modem received its name.

How Does Your Sportster Winmodem
33600 & x2/56K∗Work ?
With your Sportster Winmodem 33600 & x2/56K*, you can move
beyond the boundaries of your computer — around the world, if
you’d like. You can fax a graphic to an overseas supplier, update
files on your computer at work from your computer at home,
surf the Internet…he list goes on.
Quickly
The Sportster 33600 Winmodem Voice modem installed in your
PC can transmit and receive data as well as transmit and
receive facsimile documents as follows:
a) Utilizing new X2 technology the modem can receive up to
56Kbits per second to enable fast download of web pages
and images. Contact your local Internet provider to ascertain
the availabilty of this service. The actual speed achieved will
depend on your location relative to your ISP and in particuliar
the method used by your local telephone company to provide
normal telephone service.
b) Conforming to international standards the modem will
transmit and receive data at up to 33.6 Kbit/s dependant on
the corresponding modem’s capability.
c) Utilizing the preloaded software in your machine the modem
will transmit and receive facsimile documents at speeds up to
14.4 Kbit/s using ITU standard V17 protocol.

and correct errors during a transmission (V.42/MNP 2-4 error
control.)
Efficiently
The Sportster Winmodem 33600 & x2/56K ’s data compression
feature can pack data down to a fraction of its original size.
It can also de-compress data compressed by the remote
modem
(V.42 bis /MNP 5 data compression.)
With Windows
Sportster Winmodem 33600 & x2/56K is designed to operate
exclusively in the Windows environment with fully-compliant
Windows software. It will not work in MS-DOS or in an MS-DOS
shell under Windows.

DIGITAL PHONE LINE.
Since some homes and most businesses have digital lines,
before plugging your Sportster Winmodem 33600 & x2/56K into
a jack you are unsure about, ask the person in charge of the
phone system if the line is digital.
Other Features
Plug and Play
Plug and Play allows a computer to configure the modem's
settings automatically. Your computer sets the optimal
configuration for the modem and your software applications
automatically adjust to that configuration.
Once your system sets the configuration, it will use this
configuration every time you turn on your machine. In order to
use this feature, you must have either a Plug and Play BIOS or
Windows 95.

Speakerphone
Working with the Sound Card
The modem fitted in your Pc is equipped with jack sockets for
speakers and microphone on the rear panel as well as an
internal connection that goes directly to the sound card (if fitted).
It is recommended that for higher quality recording and playing
of messages and playing of audio files, your speakers and
microphones are connected on the sound card and not directly
to the jack sockets on the modem. This will enable the sound
output and record input to be regulated via the mixer control
panel.
In the event that you do not have a sound card fitted, powered
speakers and a microphone can be connected directly to the
sockets on the modem.
Personal Voice Mail
Using this feature, you can send voice greetings and record
voice messages like a standard answering machine with several
“voice mailboxes” on one system. You can even access your
voice messages remotely. Your modem will autodetect incoming
fax/voice/data calls and provides fax-on-demand services you
can tailor to your needs.

an available IRQ. (NOTE: Do not check the Let Plug &
Play configure… option.)
• For the I/O address: Choose any on the list.
• For the IRQ: The COM port/IRQ combinations
shown here work with most computer set-ups:
If you choose
this COM port :
Then try
this IRQ:
14
23
3 5, 7 or 9
4 5, 7 or 9
If you have a sound card, SCSI card, or game card, it might be
using IRQ 5 or 7. Do not make 5 or 7 your first choice then,
because it might not be available.
If the configuration you’ve chosen works , you should be able to
find the Sportster Winmodem 33600 & x2/56K group in the
Program Manager window. If you can find this group, you’re

• If you cannot select a Sportster or Courier model
from the list, try:
1. Typing this “initialization string:” AT&F1
2. And then pressing the ENTER key.
• If you’re asked for a serial port (baud) rate, set
the rate for the highest option. (115.200 bps is a
good choice for most programs.) If you experience
trouble later (unusually slow transmissions, errors in
transmissions, etc.), reduce the rate. Do not choose
28.800 bps, 14.400 bps, or 12.000 bps, however.
Sportster Winmodem 33600 & x2/56K will not work
properly at these serial port rates.
• If you have to specify the COM port being used,
refer to the number you wrote on the first page of this
manual.
If you are asked to specify a flow control setting, choose
RTS/CTS for hardware flow control (highly recommended) or
XON/XOFF (the &F2 command) for software flow control.
Disable the type of flow control you are not using.
