tristate "PLIP (parallel port) support" |
|
depends on PARPORT |
|
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.rst>. 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.
