A modem is a computer peripheral that allows you to connect and communicate with other computers via telephone
lines. Modems allow you to combine the power of your computer with the global reach of the telephone system.
Because ordinary telephone lines cannot carry digital information, a modem changes the digital data from your
computer into analog data, a format that can be carried. In a similar manner, the modem receiving the call then
changes the analog signal back into digital data that the computer can digest. This shift of digital data into analog
data and back again allows two computers to “speak” with one another. Called modulation/ demodulation, this
transformation of signals is how the modem received its name.
With a modem and a standard telephone line, you can send faxes to the office or important customers without
leaving your computer. And with an online or internet connection, you can share recipes with fellow gourmets, catch
up on the latest news, view a weather map from Singapore, keep in touch with distant friends by electronic mail,
surf the World Wide Web and much more.

Speakerphone
You can use your new Sportster as a full-duplex speakerphone without the echoing sound of some speakerphones.
The full-duplex feature allows you to speak at the same time as someone on the other end without losing any sound
quality. This affords you all the convenience of a speakerphone without the extra hardware and cords for the home
or office.
External modems have built-in microphones and you can attach a microphone and speaker to the internal models.
Personal Voice Mail
With Personal Voice Mail, your modem is a full-featured messaging system offering business-quality voice mail
features in the convenience of your home or office.
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.

Plug and Play Feature
Your new modem features Plug and Play installation, the fastest, easiest way to add new devices to your PC.
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.
Most operating systems, including Windows 95, support Plug and Play. Configuring your new modem with
Windows 95 is addressed near the end of this chapter.
Consult your software manual or computer manufacturer to see whether your system supports the Plug and Play
features.
Once your system sets the configuration, it will use this configuration every time you turn on your machine.
In order to activate the Plug and Play feature with your modem, you must take off all the contacts on the COM port
and IRQ jumpers on the modem. You will be able to tell which COM port your modem has been set to by having
your communications software search for the COM port. Later sections of this chapter will explain how to locate
and change the COM port and IRQ settings.
Locating the Jumpers
Using the drawing of the modem to the right, find where the COM port and IRQ jumpers are located on your

Note: If you are using the communications software included with your modem, you can disregard this chapter.
However, if you are using your own communications software, please refer to the software's manual and this
chapter.
Communications software allows you to change settings and issue commands to your modem.
The software included with your modem is preconfigured for optimal performance with the Sportster. Refer to the
software manual for any additional information. Be sure to install software after the modem is installed.
Configuring Your Modem
Some programs allow you to select your modem type from a menu. Select the appropriate U.S. Robotics Sportster
High Speed modem. If yours is not present, try a Courier Dual Standard, V.32 bis, V.FC, or V. 34.
Other programs require you to enter an initialization string in the software Modem Setup screen. If this is the case,
enter the following string to initialize your modem with the optimal settings for your pc:
AT&F1<Enter>.
These settings include: hardware flow control, a fixed serial port rate, and full result codes.
If you must use software flow control, enter the following string:
AT&F2<Enter>

14
Configuring Your Software
1. Turn on your computer (and modem if you have an external).
2. Install your communications software (refer to the software's documentation).
3. If you have an external modem, follow this step. Otherwise, skip to step 4.
· From DOS, change to your Windows directory and type MSD.
· Type C for COM Ports. Find the line UART Chip Used and match it with the COM Port
column to which you attached your modem to determine the UART type (usually 8250,
16450, or 16550). Remember your UART type for step 5.
4. Start your communications software program.
5. Set the software's serial port (baud) rate based on your UART type. Also, fix or lock the serial port rate (if
referred to as autobaud, select OFF).
UART Serial Rate
16550 115.2K or 57.6K bps
16450 38.4K bps
8250 19.2K bps
Note: All internal Sportsters have a 16550 UART on the modem. Some software packages offer 12.000 bps
as a serial port rate. Do NOT select this option. Your modem will not function properly with that setting.
6. Specify the serial (COM) port used by the modem in your communications software if working in
DOS. The default configuration on internal modems is COM 2, IRQ 3, unless you have changed it.
For external modems, check the serial port to which your modem is connected.
7. Specify your modem's flow control setting: RTS/CTS for hardware flow control (highly
recommended) or XON/XOFF for software flow control. You should disable the flow control
method you are not using.

15
Testing Your Installation
1. To test your modem and software installation, perform the software function that puts your computer
in Terminal mode. In Terminal mode, a cursor appears on your screen, allowing you to send commands
directly to the modem.
2. To determine if your computer and modem are communicating properly, type the following
command: AT E1 Q V1<Enter>
· If the COM port and IRQ settings are correct on your modem and in your software, the
modem responds: OK
· If the characters you type do not appear, no OK appears, or double characters appear, see
the Troubleshooting section in this guide.

16
7URXEOHVKRRWLQJ
Before the modems connect…
If your modem doesn't respond to any AT commands,
· Make sure the modem is on.
· Make sure you selected the correct COM port and IRQ in your communications software, and/or in your
Windows Control Panel.
· Make sure the computer is in Terminal mode.
· Type in all upper (AT) or lower (at) case.
· There may be a COM port/IRQ conflict. Refer back to Internal Installation. You will need to remove your
modem from the PC and change your COM port and IRQ settings. Lift the black plastic shunts off
the modem and replace the COM port shunt to 3 and the IRQ shunt to 5. If you change your COM port and IRQ
settings, also make the changes in your software and in Windows.
If your modem displays double characters on your monitor,
· Both your modem's and software's local echoes are on and need to be turned off by typing the command
ATE0<Enter>.
If your modem doesn't go off hook to dial a number or doesn't answer the phone,
· Make sure the phone cord is connect to the jack on the modem labeled TELCO and to a phone wall jack.
· Review your software manual to see what DTR operations are required.
· Make sure that your software has auto answer enabled.

17
If both modems exchange carrier signals but fail to establish a communications link,
· Place the call again. The telephone company routes all calls, even local calls, differently each time you
call.
· Call a different modem to see if the problem persists. The problem may be with the modem you
first tried to call.
If your modem doesn't connect at 2400 bps with a 2400 bps modem,
· The remote modem might be an older 2400 bps modem that does not support error control. Disable
error control with the following command: AT&M0<Enter>
· Try connecting with the remote modem again.
· When the call is finished, remember to reset the modem: ATZ<Enter>
During data transfer…
If your screen displays random or garbage characters,
· Set your software to the same word length, parity, and Stop bits as the remote modem.
· Make sure that your software and modem are set to the same flow control setting and to either a fixed or
variable serial port rate.
· Type the following command to load the template that enables hardware flow control as well as other
optimal settings. AT&F1<Enter>
· Disable any Terminate and Stay Resident (TSR) programs running in the background.
