PART I: SECTION A: INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X

D KEY POINT: Accessories cannot share
COM ports and should not share IRQs.
When accessories try to share settings,
they will either not work properly or not
work at all. This section of the manual will
help you understand the COM/IRQ
settings on your new Sportster.
U.S. Robotics has set your Sportster to use
COM 2 and IRQ 3. This is the industry
standard for modem settings. In most cases,
these settings will work. In some instances,
however, these settings are already being used
by another accessory, such as a sound card or
another COM port. We recommend that you
run the ComTest program (on the
Connections CD) to determine what settings
your modem should use.
NOTE: Some communications
software programs require a particular
setting for your modem. (RapidComm
Voice, which shipped with your modem,
does not.) If you wish to use a program
other than RapidComm Voice, now is a
good time to read that software’s manual
to determine what setting is required.
How to Use ComTest to
Determine Your Modem’s
Settings
1. Insert your Connections CD into your CD-
ROM drive.
2. In the Windows Program Manager, select
Run from the File menu. Enter the file name
as d:\comtest.exe. This starts ComTest,
