Each of the virtual modems is available for a different application. For instance,
the ISDN FAX (G3) modem is configured for fax applications, while ISDN RAS
can be used for remote-access connections to remote computers.

can be used for remote-access connections to remote computers.
The default configurations of the virtual modems allow them to be used
immediately in most conventional implementations without any further
configuration required. However, it is also possible to adapt the ISDN CAPI Port
Device Driver for special cases such as the configuration of the Internet
connection and RAS (see ” Modem Settings Using Registry Commands”).

Programs that use the CAPI interface directly can exploit the CAPI Port modem to
use the second B channel for their own use, parallel to an existing Dial-Up
Networking connection. This is possible because the B-channel assignments are
performed by CAPI automatically.

The virtual modems ISDN FAX (G3) and ISDN Analog Modem (V.32bis) can
only be used with passive ISDN-Controllers if the ISDN-Controller's device
driver software supports these services. Contact the distributor or
manufacturer of your ISDN-Controller for more information.

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.
