Setting Up Your Faxmodem with
Windows 3.1 or 3.11
If you are running Windows 3.1 or 3.11, you need to run the
SETPORT utility from your DOS prompt.
If your computer has a CD-ROM drive, insert the disc that
came with your faxmodem. Otherwise, Insert the disk labeled
BitWare Disk 2 in your floppy drive.
From the DOS prompt, type D:\ (or the drive letter of the
correct drive) and press Enter. At the D:\ (or A:\ or other
drive if you’re installing from floppies) prompt, type cd
setport and press Enter. This opens the SETPORT
directory.
This directory contains utilities that help you configure your
faxmodem’s COM port and IRQ settings.
Type setport 3 and press Enter. The program tries to set up
the faxmodem on COM 3. In almost all circumstances,
setport 3 successfully sets the modem to COM3 and a free
IRQ, usually 12 or 11.
Once the program finds a free IRQ, it tries to communicate
with the faxmodem using these settings. If successful, the
program asks if you want it to automatically modify your
AUTOEXEC.BAT and SYSTEM.INI files.
We strongly recommend that you answer Yes to these
prompts.
If unsuccessful, PORTWIZ checks more IRQs until it finds
one that works. PORTWIZ checks the following IRQs in
order: 12, 11, 15, 10, 7, and 5.
If you don’t get an error message at this point and your
computer does not start behaving erratically, skip to
step 5; your faxmodem hardware is installed.
If you do have a problem, continue below.
Repeat step 3, but use COM 4 (i.e., type setport 4 and
press Enter). If COM 4 results in an error message, try
COM 1 and then COM 2.
Even if SETPORT is successful, you may still run into a
conflict with another peripheral, such as a mouse, a video
card, or a sound card. This happens because SETPORT is
