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