(For details see 8 <http://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). 13 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. 17 18if ISDN_CAPI 19 20config CAPI_TRACE 21 bool "CAPI trace support" 22 default y 23 help 24 If you say Y here, the kernelcapi driver can make verbose traces 25 of CAPI messages. This feature can be enabled/disabled via IOCTL for 26 every controller (default disabled). 27 This will increase the size of the kernelcapi module by 20 KB. 28 If unsure, say Y. 29 30config ISDN_CAPI_CAPI20 31 tristate "CAPI2.0 /dev/capi20 support" 32 help 33 This option will provide the CAPI 2.0 interface to userspace 34 applications via /dev/capi20. Applications should use the 35 standardized libcapi20 to access this functionality. You should say 36 Y/M here. 37 38config ISDN_CAPI_MIDDLEWARE 39 bool "CAPI2.0 Middleware support" 40 depends on ISDN_CAPI_CAPI20 && TTY 41 help 42 This option will enhance the capabilities of the /dev/capi20 43 interface. It will provide a means of moving a data connection, 44 established via the usual /dev/capi20 interface to a special tty 45 device. If you want to use pppd with pppdcapiplugin to dial up to 46 your ISP, say Y here. 47 48config ISDN_CAPI_CAPIDRV_VERBOSE 49 bool "Verbose reason code reporting" 50 depends on ISDN_CAPI_CAPIDRV 51 help 52 If you say Y here, the capidrv interface will give verbose reasons 53 for disconnecting. This will increase the size of the kernel by 7 KB. 54 If unsure, say N. 55 56endif 57
