11. Implementations of the IBM International ISDN PC Card 69
first and assign it a free COM port between COM1 and COM4. Then
install the IBM International ISDN PC Card, followed by cFos.
• You may be able to assign two different cFos modem emulations the same
COM port–assigning both ”cFos ISDN, FAX via CAPI” and “cFos ISDN,
Internet, Sync PPP over HDLC” to COM5 for example–and then use the
two virtual modems in alternation.
This practice is not recommended, however, since it may cause problems in
cFos. If possible, avoid configurations with shared COM ports!
2. When using SystemSoft's CardWizard under Windows 95, the CardWizard
software may not be able to detect the IBM International ISDN PC Card
properly. Removing and reinserting the ISDN PC Card allows CardWizard to
detect it. However, this may result in cFos becoming unavailable. For this
reason it is therefore strongly recommended that you remove SystemSoft's
CardWizard from your system before installing the IBM International ISDN
PC Card.
3. During the installation you may enter an MSN, although this is not required.
However, if your ISDN line is a PBX extension, cFos may be unable to dial. In
this case, reconfigure cFos to use an MSN. This problem is due to a limitation
of some currently available ISDN PBX systems.
4. In all versions of Windows, the cFos installer also automatically installs the
modem emulations “cFos ISDN, Internet, Sync PPP over HDLC” and the
“cFos ISDN, Internet, add. Sync PPP over HDLC” by default. Select at least
two COM ports during the cFos installation.
5. You may find that some software applications install a set of drivers called the
CAPI Port Driver. The CAPI Port Driver is similar to cFos, but offers fewer
functions and features. This is not a problem: cFos and the CAPI Port Driver
can coexist on a Windows computer.
Installing cFos in Windows 95, Windows 98, and Windows Me
IBM recommends to download, buy, and use the latest cFos version or use the one
provided on the CD for the IBM International ISDN PC Card for use with non-
CAPI 2.0 compliant software. For further assistance with cFos, see one of the
