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

32	  To compile this driver as a module, choose M here: the module
33	  will be called x25. If unsure, say N.
