5 This provides CAPI (the Common ISDN Application Programming
6 Interface) Version 2.0, a standard making it easy for programs to
7 access ISDN hardware in a device independent way. (For details see
8 <https://www.capi.org/>.) CAPI supports making and accepting voice
9 and data connections, controlling call options and protocols,
10 as well as ISDN supplementary services like call forwarding or
11 three-party conferences (if supported by the specific hardware
12 driver).

14 This subsystem requires a hardware specific driver.
15 See CONFIG_BT_CMTP for the last remaining regular driver
16 in the kernel that uses the CAPI subsystem.

21 If you say Y here, the kernelcapi driver can make verbose traces
22 of CAPI messages. This feature can be enabled/disabled via IOCTL for
23 every controller (default disabled).

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