		A Parallel Line IP SANA2 Device Driver

		  by Michael Balzer & Oliver Wagner

			*** BETA-RELEASE 38.11 ***





1. Overview

PLIP is a network device driver conforming to the SANA2 standard.  It
allows linking of two Amigas using their parallel ports.  Transfer speed
is around 50 kbyte/sec.  The complete low level transfer protocol is
integrated in the device driver, including port arbitration handshaking and
interrupt driven reads.  Although the transfer process itself is cpu
intensive, the device needs no cpu resources when no transfer is in
progress.

PLIP is intended as a low-cost networking solution, since the capabilities
of the parallel hardware are somewhat limited.  However, it gives much
better results than SLIP and leaves the serial port free.

2. Installation

Just copy plip.device to devs:networks.  See the documentation of your
networking package for further installation steps.

Since PLIP only allows two hosts to be linked together, addressing is
limited to 1 Bit.  One host uses plip.device, Unit 0, the other
plip.device, Unit 1.  The device will not work if both machines use the
same unit number.

3. Cable

 D0-D7/BUSY/POUT   to   D0-D7/BUSY/POUT
 ACK		   to   STROBE
 STROBE		   to   ACK
 GND		   to   GND

Note that this is *NOT* the ParNet connection standard used by several old
parallel drivers.

4. Beta

PLIP is not tested yet, so use on your own risk.  Please send bug reports
to:

	o.wagner@aworld.aworld.de
	m.balzer@aworld.aworld.de

Please exactly state the machine configuration which causes PLIP to fail.

6. History

V37.11
------
- small speedups in transmission handshaking
- now uses utility library for parsing the buffer managment taglist

V38.10
------
- fixed bug with configuration during startup
- default MTU reduced to 1024 bytes

V38.11 (beta)
-------------
- added tracktype support (beta) in order to make PLIP work
  in conjunction with AmiTCP
- removed autoinit for dos.library
