0005 This provides CAPI (the Common ISDN Application Programming
0006 Interface) Version 2.0, a standard making it easy for programs to
0007 access ISDN hardware in a device independent way. (For details see
0008 <https://www.capi.org/>.) CAPI supports making and accepting voice
0009 and data connections, controlling call options and protocols,
0010 as well as ISDN supplementary services like call forwarding or
0011 three-party conferences (if supported by the specific hardware
0012 driver).

0014 This subsystem requires a hardware specific driver.
0015 See CONFIG_BT_CMTP for the last remaining regular driver
0016 in the kernel that uses the CAPI subsystem.

0021 If you say Y here, the kernelcapi driver can make verbose traces
0022 of CAPI messages. This feature can be enabled/disabled via IOCTL for
0023 every controller (default disabled).

0028 This option will enhance the capabilities of the /dev/capi20
0029 interface. It will provide a means of moving a data connection,
0030 established via the usual /dev/capi20 interface to a special tty
0031 device. If you want to use pppd with pppdcapiplugin to dial up to
0032 your ISP, say Y here.
