58c2ecf20Sopenharmony_ci	  This provides CAPI (the Common ISDN Application Programming
68c2ecf20Sopenharmony_ci	  Interface) Version 2.0, a standard making it easy for programs to
78c2ecf20Sopenharmony_ci	  access ISDN hardware in a device independent way. (For details see
88c2ecf20Sopenharmony_ci	  <https://www.capi.org/>.)  CAPI supports making and accepting voice
98c2ecf20Sopenharmony_ci	  and data connections, controlling call options and protocols,
108c2ecf20Sopenharmony_ci	  as well as ISDN supplementary services like call forwarding or
118c2ecf20Sopenharmony_ci	  three-party conferences (if supported by the specific hardware
128c2ecf20Sopenharmony_ci	  driver).
138c2ecf20Sopenharmony_ci
148c2ecf20Sopenharmony_ci	  This subsystem requires a hardware specific driver.
158c2ecf20Sopenharmony_ci	  See CONFIG_BT_CMTP for the last remaining regular driver
168c2ecf20Sopenharmony_ci	  in the kernel that uses the CAPI subsystem.

218c2ecf20Sopenharmony_ci	  If you say Y here, the kernelcapi driver can make verbose traces
228c2ecf20Sopenharmony_ci	  of CAPI messages. This feature can be enabled/disabled via IOCTL for
238c2ecf20Sopenharmony_ci	  every controller (default disabled).

288c2ecf20Sopenharmony_ci	  This option will enhance the capabilities of the /dev/capi20
298c2ecf20Sopenharmony_ci	  interface.  It will provide a means of moving a data connection,
308c2ecf20Sopenharmony_ci	  established via the usual /dev/capi20 interface to a special tty
318c2ecf20Sopenharmony_ci	  device.  If you want to use pppd with pppdcapiplugin to dial up to
328c2ecf20Sopenharmony_ci	  your ISP, say Y here.
