7 Installing the Driver
Software in Windows 3.x
Specially developed driver software is provided for use in Mi-
crosoft Windows 3.x. This 32-bit device driver (VxD) exploits
the potential of Windows’ “Protected Mode”.
The CAPI provided supports both Windows applications and
applications and DOS boxes running at the same time.
You do not need to load a DOS-based CAPI before starting
Windows. If you wish to use DOS CAPI applications, use the
DOS box.
US only: In addition to the D-channel protocol, ISDN us-
ers in the USA must find out their SPID.
SPID stands for Service Profile IDentifier. A SPID is a number
assigned by your ISDN service provider to each subscriber in-
terface. SPIDs let the ISDN switch know which ISDN services
a given logical terminal (ISDN device) can access. This is par-
ticularly important for ISDN telephones.

To install, proceed as follows:
1. Start Windows 3.x.
