IBM 19K5716 manual Prerequisites for the Capi Port installation

In principle, the CAPI Port inserts an intermediary 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.

Note: The CAPI 2 0 interface is not restricted to Europe - it works all over the world!

Prerequisites for the CAPI Port installation

Before the CAPI Port drivers can be installed, the device drivers for the IBM International ISDN PC Card must be installed on your system.

If you already have CAPI Port drivers installed on your system, reinstallation may not be possible without removing the older driver versions. See “Removing the CAPI Port Drivers” on page 152 for details.
