1 # 2 # Parallel Line Internet Protocol (PLIP) network device configuration 3 # 4 5 config PLIP 6 tristate "PLIP (parallel port) support" 7 depends on PARPORT 8 ---help--- 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.
