178 IBM ISDN PC Card:User’s Guide
The fax functions of MS Exchange/Outlook and other Fax Group 3 applications
can be used through the virtual CAPI Port modem ISDN FAX (G3).
Installing / removing the ISDN CAPI Port device driver
If you have not yet done so, first install the CAPI 2.0 device drivers for your
ISDN-Controller according to the instructions in the manual.
Before starting installation of the ISDN CAPI Port Device Driver, note the
following:
• During installation up to eight different virtual modems are created, each of
which fulfills a different function.
• To use the virtual modems ”ISDN FAX (G3)” and ”ISDN Analog Modem
(V.32bis)” with passive ISDN-Controllers, the device driver software of your
ISDN-Controller must support these services. Contact the manufacturer for
more information.
• The virtual modem ”ISDN Analog Modem (V.32bis)” can be used only with
passive ISDN-Controllers. The analog/digital conversion is performed by the
computer's CPU. A Pentium computer with 133 MHz and at least 32 MB RAM
will provide optimal performance.
• It might be necessary to assign COM ports to the virtual modems. This is the
case when using Dial-Up Networking software which can access only COM
ports (such as older versions for Windows 3.x). See the instructions in the
section ” Using Data Communications Software with an Emulated COM
Port”. Before making any assignments, check which COM ports are already
in use by other hardware devices like serial interfaces.

1. Insert the disk or CD with the ISDN CAPI Port Device Driver in the
