+config CAPI_TRACE
+ bool "CAPI trace support"
+ default y
+ help
+ 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.
+
+config ISDN_CAPI_CAPI20
+ tristate "CAPI2.0 /dev/capi20 support"
+ help
+ 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.
+
+config ISDN_CAPI_MIDDLEWARE
+ bool "CAPI2.0 Middleware support"
+ depends on ISDN_CAPI_CAPI20 && TTY
+ help
+ 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.
+
+config ISDN_CAPI_CAPIDRV
+ tristate "CAPI2.0 capidrv interface support"
+ depends on ISDN_I4L
+ help
+ This option provides the glue code to hook up CAPI driven cards to
+ the legacy isdn4linux link layer. If you have a card which is
+ supported by a CAPI driver, but still want to use old features like
+ ippp interfaces or ttyI emulation, say Y/M here.
+
+config ISDN_CAPI_CAPIDRV_VERBOSE
+ bool "Verbose reason code reporting"
+ depends on ISDN_CAPI_CAPIDRV
+ 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.
