IBM ISDN PC Card:User’s Guide

Anywhere 9.x, and many others. A list of CAPI 2.0-compliant software products 
can be found in the World Wide Web at

However, many programs are not CAPI 2.0-compliant, including AOL 5.0, the 
CompuServe 4.0 dialer and other applications. By installing cFos you can equip 
your computer with a set of drivers that simulate analog modems, but 
communicate over the digital ISDN line. In other words, cFos installs a set of 
virtual modems which allow you to use practically any software designed to 
communicate with a modem.

In principle, cFos inserts an additional layer between the application you use and 
the CAPI 2.0 interface. It interprets the modem communication program's AT 
commands and converts them into CAPI 2.0-compliant API calls, thus allowing 
software which was not designed for ISDN communication to use your ISDN line.

 Using cFos does not guarantee that your non-CAPI compliant software 
will work with the IBM International ISDN PC Card. If this is the case, 
please consult the User’s Guide for your software or your software 
support.

The CAPI 2.0 interface is not restricted to Europe – it works all over the world.

Before you can install cFos, the device drivers for the IBM International ISDN PC 
Card must be installed in your system. Please read the corresponding chapters in 
this User's Guide to install the device drivers for the IBM International ISDN PC 
Card.

1. The following installation sections contain instructions for installing cFos. In 

the cFos Setup program, you may find that almost all COM ports have been 
selected by default. When configuring these settings, observe the following:

•

Avoid selecting COM1 and COM2 if possible. Selecting these ports may 
cause conflicts. The safest method is to select only COM ports above 
COM4, unless your application program only supports COM1 to COM4. 
If this is the case, try to use either COM4 (recommended) or COM3 (if you 
have no alternative).

•

Activating all COM ports will consume a considerable amount of system 
memory. Try to use cFos with only as many COM ports as you actually 
need. No more than two or three COM ports are recommended.

•

Using cFos with all the available COM ports results in a very large status 
window.

•

If you use both an analog modem and the IBM International ISDN PC 
Card, and you have selected all COM ports in the cFos Setup–that is, 
COM1 to COM9 are all configured for use by cFos–then your analog 
modem may be assigned the next free COM port available, such as 
COM10. It is strongly recommended that you install the analog modem
