  6. ---help---
  7. X.25 is a set of standardized network protocols, similar in scope to
  8. frame relay; the one physical line from your box to the X.25 network
  9. entry point can carry several logical point-to-point connections
  10. (called "virtual circuits") to other computers connected to the X.25
  11. network. Governments, banks, and other organizations tend to use it
  12. to connect to each other or to form Wide Area Networks (WANs). Many
  13. countries have public X.25 networks. X.25 consists of two
  14. protocols: the higher level Packet Layer Protocol (PLP) (say Y here
  15. if you want that) and the lower level data link layer protocol LAPB
  16. (say Y to "LAPB Data Link Driver" below if you want that).
  17. You can read more about X.25 at <http://www.sangoma.com/tutorials/x25/> and
  18. <http://docwiki.cisco.com/wiki/X.25>.
  19. Information about X.25 for Linux is contained in the files
  20. <file:Documentation/networking/x25.txt> and
  21. <file:Documentation/networking/x25-iface.txt>.
  22. One connects to an X.25 network either with a dedicated network card
  23. using the X.21 protocol (not yet supported by Linux) or one can do
  24. X.25 over a standard telephone line using an ordinary modem (say Y
  25. to "X.25 async driver" below) or over Ethernet using an ordinary
  26. Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
  27. Driver" and "LAPB over Ethernet driver" below).
  28. To compile this driver as a module, choose M here: the module
  29. will be called x25. If unsure, say N.
