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).

- standardized libcapi20 to access this functionality. You should say
- Y/M here.

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.
