This provides CAPI (the Common ISDN Application Programming
|
||
|
|
Interface) Version 2.0, a standard making it easy for programs to
|
||
|
|
access ISDN hardware in a device independent way. (For details see
|
||
|
|
<http://www.capi.org/>.) CAPI supports making and accepting voice
|
||
|
|
and data connections, controlling call options and protocols,
|
||
|
|
as well as ISDN supplementary services like call forwarding or
|
||
|
|
three-party conferences (if supported by the specific hardware
|
||
|
|
driver).
|
||
|
|
|
||
|
|
This subsystem requires a hardware specific driver.
|
||
|
|
See CONFIG_BT_CMTP for the last remaining regular driver
|
||
|
|
in the kernel that uses the CAPI subsystem.

If you say Y here, the kernelcapi driver can make verbose traces
|
||
|
|
of CAPI messages. This feature can be enabled/disabled via IOCTL for
|
||
|
|
every controller (default disabled).
|
||
|
|
This will increase the size of the kernelcapi module by 20 KB.
|
||
|
|
If unsure, say Y.

This option will provide the CAPI 2.0 interface to userspace
|
||
|
|
applications via /dev/capi20. Applications should use the
|

|
|
standardized libcapi20 to access this functionality. You should say
|

|
|
Y/M here.

This option will enhance the capabilities of the /dev/capi20
|
||
|
|
interface. It will provide a means of moving a data connection,
|
||
|
|
established via the usual /dev/capi20 interface to a special tty
|
||
|
|
device. If you want to use pppd with pppdcapiplugin to dial up to
|
||
|
|
your ISP, say Y here.

help
|

If you say Y here, the capidrv interface will give verbose reasons
|

|
|
for disconnecting. This will increase the size of the kernel by 7 KB.
|

|
|
If unsure, say N.
