9	  PLIP (Parallel Line Internet Protocol) is used to create a
10	  reasonably fast mini network consisting of two (or, rarely, more)
11	  local machines.  A PLIP link from a Linux box is a popular means to
12	  install a Linux distribution on a machine which doesn't have a
13	  CD-ROM drive (a minimal system has to be transferred with floppies
14	  first). The kernels on both machines need to have this PLIP option
15	  enabled for this to work.
16
17	  The PLIP driver has two modes, mode 0 and mode 1.  The parallel
18	  ports (the connectors at the computers with 25 holes) are connected
19	  with "null printer" or "Turbo Laplink" cables which can transmit 4
20	  bits at a time (mode 0) or with special PLIP cables, to be used on
21	  bidirectional parallel ports only, which can transmit 8 bits at a
22	  time (mode 1); you can find the wiring of these cables in
23	  <file:Documentation/networking/PLIP.txt>.  The cables can be up to
24	  15m long.  Mode 0 works also if one of the machines runs DOS/Windows
25	  and has some PLIP software installed, e.g. the Crynwr PLIP packet
26	  driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>)
27	  and winsock or NCSA's telnet.
28
29	  If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well
30	  as the NET-3-HOWTO, both available from
31	  <http://www.tldp.org/docs.html#howto>.  Note that the PLIP
32	  protocol has been changed and this PLIP driver won't work together
33	  with the PLIP support in Linux versions 1.0.x.  This option enlarges
34	  your kernel by about 8 KB.
35
36	  To compile this driver as a module, choose M here. The module
37	  will be called plip. If unsure, say Y or M, in case you buy
38	  a laptop later.
