  	---help---
  	  X.25 is a set of standardized network protocols, similar in scope to
  	  frame relay; the one physical line from your box to the X.25 network
  	  entry point can carry several logical point-to-point connections
  	  (called "virtual circuits") to other computers connected to the X.25
  	  network. Governments, banks, and other organizations tend to use it
  	  to connect to each other or to form Wide Area Networks (WANs). Many
  	  countries have public X.25 networks. X.25 consists of two
  	  protocols: the higher level Packet Layer Protocol (PLP) (say Y here
  	  if you want that) and the lower level data link layer protocol LAPB
  	  (say Y to "LAPB Data Link Driver" below if you want that).

  	  You can read more about X.25 at <http://www.sangoma.com/tutorials/x25/> and
  	  <http://docwiki.cisco.com/wiki/X.25>.

  	  Information about X.25 for Linux is contained in the files
  	  <file:Documentation/networking/x25.txt> and
  	  <file:Documentation/networking/x25-iface.txt>.
  
  	  One connects to an X.25 network either with a dedicated network card
  	  using the X.21 protocol (not yet supported by Linux) or one can do
  	  X.25 over a standard telephone line using an ordinary modem (say Y
  	  to "X.25 async driver" below) or over Ethernet using an ordinary
  	  Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
  	  Driver" and "LAPB over Ethernet driver" below).
  
  	  To compile this driver as a module, choose M here: the module
  	  will be called x25. If unsure, say N.
