1# SPDX-License-Identifier: GPL-2.0-only 2config CAPI_TRACE 3 bool "CAPI trace support" 4 default y 5 help 6 If you say Y here, the kernelcapi driver can make verbose traces 7 of CAPI messages. This feature can be enabled/disabled via IOCTL for 8 every controller (default disabled). 9 This will increase the size of the kernelcapi module by 20 KB. 10 If unsure, say Y. 11 12config ISDN_CAPI_CAPI20 13 tristate "CAPI2.0 /dev/capi20 support" 14 help 15 This option will provide the CAPI 2.0 interface to userspace 16 applications via /dev/capi20. Applications should use the 17 standardized libcapi20 to access this functionality. You should say 18 Y/M here. 19 20config ISDN_CAPI_MIDDLEWARE 21 bool "CAPI2.0 Middleware support" 22 depends on ISDN_CAPI_CAPI20 && TTY 23 help 24 This option will enhance the capabilities of the /dev/capi20 25 interface. It will provide a means of moving a data connection, 26 established via the usual /dev/capi20 interface to a special tty 27 device. If you want to use pppd with pppdcapiplugin to dial up to 28 your ISP, say Y here. 29 30config ISDN_CAPI_CAPIDRV 31 tristate "CAPI2.0 capidrv interface support" 32 depends on ISDN_I4L 33 help 34 This option provides the glue code to hook up CAPI driven cards to 35 the legacy isdn4linux link layer. If you have a card which is 36 supported by a CAPI driver, but still want to use old features like 37 ippp interfaces or ttyI emulation, say Y/M here. 38 39config ISDN_CAPI_CAPIDRV_VERBOSE 40 bool "Verbose reason code reporting" 41 depends on ISDN_CAPI_CAPIDRV 42 help 43 If you say Y here, the capidrv interface will give verbose reasons 44 for disconnecting. This will increase the size of the kernel by 7 KB. 45 If unsure, say N. 46
