Subject: Using The WinFax TSR With A Fax/Modem On IRQ5

Situation:
==========
You want to use the WinFax TSR to receive faxes in DOS with a fax/modem 
on IRQ5.

Solution:
=========
Perform the following procedure to change the configuration of the
WinFax TSR:

1.  Open the WINFAX.INI file in Windows Notepad, or any other basic text 
    editor. The WINFAX.INI file is usually located in your WinFax 
    directory (for example C:\WINFAX).

2.  In the [TSR] section of the WINFAX.INI, make the following changes:

    a)  Place a semicolon at the beginning of the PORT= line to "remark 
        out" the line. For example:

          ;PORT=1

    b)  Add the line:

          ComIRQ=5

    c)  Add the line ...

          ComIOBase=xxx

        ... where xxx is the address of the COM port to which your 
        fax/modem is connected, as follows:

          COM Port   Address

          COM 1        3f8
          COM 2        2f8
          COM 3        3e8
          COM 4        2e8

Notes:  Specify the above addresses using lower case letters (for
        example, use "3f8" not "3F8").

        If you have an IBM PS/2 system, leave the base address 
        configuration at the default settings of 2e8 for COM3 and 2e0 
        for COM4.

3.  Save the changes to your WINFAX.INI and exit the text editor.

Note:   This procedure reflects standard base address configurations for 
        most computers. Consult your hardware dealer or fax/modem 
        manufacturer if this procedure does not work with your computer 
        system.
