| 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). |

| 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. |
