Product: WinFax PRO 3.0, WinFax PRO 2.0
Document No.: 2033
Document Date: October 7, 1993
======================================================================
Subject: OS/2 v2.0 and v2.1 Operating System--Running WinFax
Situation:
==========
You have a Class 1 or Class 2 Fax/Modem and are running WinFax PRO
under OS/2 v2.0 or v2.1. (When running under OS/2, WinFax PRO has
access to only 1000 interrupts per second, which is not enough for
WinFax to fax at 9600 baud.)
Solution:
=========
There are a number of settings that need to be altered for WinFax PRO
to function correctly under a WIN-OS/2 v2.0 or v2.1 session:
- WinFax should be run in a full-screen WIN-OS/2 session, and any
applications that you wish to fax from must be running in the
same session.
- The session that WinFax is running under should be left in the
foreground during fax reception or transmission.
- If you have migrated WinFax from a DOS-based Windows installation,
you should reinstall WinFax from a WIN-OS/2 session. This is required
because the OS/2 migration utility will not transfer all of the
configuration information that WinFax needs.
- Change the following WIN-OS/2 settings:
IDLE_SENSITIVITY=100
IDLE_SECONDS=60
COM_HOLD=ON
HW_TIMER=ON
INT_DURING_IO=ON
Note: Setting IDLE_SENSITIVITY to 100 and IDLE_SECONDS to 60 may
reduce system performance, and may not be necessary in all
cases. For more information, see your OS/2 manual.
If you are running an Enhanced Mode Windows session under OS/2 v2.1,
make the following changes to the [386Enh] section of the SYSTEM.INI
file:
COMxBUFFER=2048
COMBOOSTTIM1024E=20
COMxFIFO=0
Note: The "x" refers to the COM port that the fax/modem is connected
to.
If you are using WinFax PRO 3.0 (April 93 or later) with a Class 1 Fax/
Modem and do not have a 16550 UART chip, insert the following lines in the
[General] section of the WINFAX.INI file:
MaxTxSpeed=7200
MaxRxSpeed=4800
Note: This will limit WinFax to sending at 7200 and receiving at 4800.
Valid entries for MaxTxSpeed are 14400, 12000, 9600, 7200 or
4800.
Valid entries for MaxRxSpeed are 14400, 9600, or 4800.
To operate at higher speeds, you must use a 16550 UART chip. OS/2 v2.1's
serial port driver uses the buffering capability of this UART to increase
the reliability of serial port communications running at 9600 baud or faster.
For more information on migration, Win-OS/2 settings, and SYSTEM.INI
settings, see your OS/2 manual.
For more information on the 16550 UART chip, see your hardware dealer or
modem anufacturer.
For more information on your modem Class and WINFAX.INI settings, see your
WinFax PRO 3.0 manual.
For information on determining your release date and updating WinFax PRO
3.0, see Technical Note 2074.
