  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. The PLIP driver has two modes, mode 0 and mode 1. The parallel
  17. ports (the connectors at the computers with 25 holes) are connected
  18. with "null printer" or "Turbo Laplink" cables which can transmit 4
  19. bits at a time (mode 0) or with special PLIP cables, to be used on
  20. bidirectional parallel ports only, which can transmit 8 bits at a
  21. time (mode 1); you can find the wiring of these cables in
  22. <file:Documentation/networking/plip.rst>. The cables can be up to
  23. 15m long. Mode 0 works also if one of the machines runs DOS/Windows
  24. and has some PLIP software installed, e.g. the Crynwr PLIP packet
  25. driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>)
  26. and winsock or NCSA's telnet.
  27. If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well
  28. as the NET-3-HOWTO, both available from
  29. <http://www.tldp.org/docs.html#howto>. Note that the PLIP
  30. protocol has been changed and this PLIP driver won't work together
  31. with the PLIP support in Linux versions 1.0.x. This option enlarges
  32. your kernel by about 8 KB.
  33. To compile this driver as a module, choose M here. The module
  34. will be called plip. If unsure, say Y or M, in case you buy
  35. a laptop later.
