Changing Windows Communications Driver

The WFXCOMM.DRV (supplied on the install disk) significantly improves Auto-
Fax performance over the default Windows driver (COMM.DRV) on many sys-
tems. This driver tends to produce more readable reports (each record is the same
height), and tends to work more reliably in multiple page mode. If your problem
is one of "readability" or if the multiple page option is not working, install the
WFXCOMM.DRV driver as explained below.
Note: This driver works with other 16 bit serial port applications. It is an improved communications
driver written by someone other than Microsoft.
1. Copy WFXCOMM.DRV from the installation disk to your Windows directory.
The file is also available on the web at: www.kiae.su:8090/kiarchive/win-
dows/drivers/.
2. Edit the "system.ini" file (section: [boot]; line: comm.drv) to read:
comm.drv=wfxcomm.drv.
This line will typically read comm.drv=comm.drv initially. Consult your Win-
dows' documentation for instructions on changing the system.ini file.
3. Reboot your system to make sure the change takes effect.
