56K Faxmodem Owner’s Manual
cally modify your AUTOEXEC.BAT and SYSTEM.INI
files.
We strongly recommend that you answer Yes to these
prompts; otherwise, you will need to run the SETPORT
utility each time you use your modem.
If unsuccessful, the software checks more IRQs until
it finds one that works. The software 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 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, read the next section, A Note About
IRQs and Conflicts, for suggestions.
Write down the COM port and IRQ setting of your fax-
modem in the Important Information page in the Quick
Start, or some other easy-to-find place. The information
is important because you may need to use it in setting
up your software applications.
If you are successful at this point, you can move on to
Chapter 2.
A Note About IRQs and Conflicts
While SETPORT.BAT and PORTWIZ.EXE do their best to
configure your faxmodem on a free IRQ, it is possible that
some of your other hardware is also configured to use
that IRQ. That is why the programs first try to query the
IRQs least likely to be used by your system.
