  4. help
  5. This provides CAPI (the Common ISDN Application Programming
  6. Interface) Version 2.0, a standard making it easy for programs to
  7. access ISDN hardware in a device independent way. (For details see
  8. <https://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. This subsystem requires a hardware specific driver.
  14. See CONFIG_BT_CMTP for the last remaining regular driver
  15. in the kernel that uses the CAPI subsystem.
  16. config CAPI_TRACE
  17. def_bool BT_CMTP
  18. help
  19. If you say Y here, the kernelcapi driver can make verbose traces
  20. of CAPI messages. This feature can be enabled/disabled via IOCTL for
  21. every controller (default disabled).

  24. help
  25. This option will enhance the capabilities of the /dev/capi20
  26. interface. It will provide a means of moving a data connection,
  27. established via the usual /dev/capi20 interface to a special tty
  28. device. If you want to use pppd with pppdcapiplugin to dial up to
  29. your ISP, say Y here.
