+ tristate "CAPI 2.0 subsystem"
+ help
+ 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.
