Setting Up Your Faxmodem for Windows 95

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 faxmodem
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.

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
another piece of your hardware also is configured to use that
IRQ. That is why the programs first try to query the IRQs least
likely to be used by your system.
In the unusual event that PORTWIZ configures your faxmodem to
use a COM port/IRQ combination that conflicts with other
hardware, either the faxmodem or the other hardware won’t work
properly. If that happens, you can run PORTWIZ by itself to try
other COM port/IRQ combinations.
Setport copies PORTWIZ into the root directory (usually C:\) the
first time you run it. After that, you can run PORTWIZ from the
DOS prompt. You can specify a COM port and IRQ for
PORTWIZ to try; the command format is:
portwiz <COM port hex address><IRQ number(s)></w>
where the COM port hex addresses are
COM 1 3f8
COM 3 3e8
COM 2 2f8
COM 4 2e8
and /w activates the Wizard mode, in which PORTWIZ edits the
AUTOEXEC.BAT and SYSTEM.INI files for you.
