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.
Repeating 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 unable to tell
that a particular IRQ setting is already assigned to another
device if that device is not being used at the time. If you get
erratic behavior, such as inconsistent modem performance or a
piece of hardware that stops working even though it worked
before, there are some advanced setup instruction in the
Owner’s Manual on the CD-ROM. If you don’t have a CD-ROM
drive but have access to one through a friend or at work, you
can print the whole manual or the appropriate pages from the
manual.
Write down the COM port and IRQ setting of your faxmodem in
the Important Information form on page 20, or some other easy-
to-find place. The information is important because you may
need to use it in setting up your software applications.
Your faxmodem
hardware is installed!
