6.1 CAPI Drivers
These drivers enable the ISDN integration of operating system functions
under Windows 95 and 98. They also permit the use of Remote Access
Service (RAS) and allow you to connect your PC to the server of an Internet
service provider by way of the TCP/IP stack and the Dial-Up Networking
application of Windows 95 and 98.
Windows 95 and 98 offer two communications models with similar
functionality: ISDN CAPI Port Driver and NDIS WAN CAPI Driver. Both
drivers are implemented in VxD technology as Windows system drivers and
are addressed through the Dial-Up Networking application, but utilise
different mechanisms and interfaces/protocols in the operating system.
Basically the same transfer rates are attained in data communications with the
two drivers. Both drivers can be installed in parallel on one system.
The BT system drivers make it possible for you to utilise communications
programs (such as Speedway!) via the Windows Dial-Up Networking
application in parallel with CAPI-based ISDN software, for example for dialling
in to the Internet.
The BT ISDN CAPI Port driver
The BT ISDN CAPI Port driver allows programs with a suitable interface
(VCOM/Modem) to also use the communications interfaces of Windows for
ISDN.
A full description of the functions of the BT ISDN CAPI Port Driver along
with detailed installation instructions may be found in the
file
CAPIPORT.HLP
in the respective folder
or
on the CD.
