| 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 | |
| <https://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. | |

| 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 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. |
