	port-handler is partly based on:
	ComHandler.c (C) 1989, 1993 by Ralph Babel, Amiga Guru Book p.643ff
	Port-Handler.asm (C) 1986 John A. Toebes, VIII (AmigaLibDisk #20)

REQUIREMENTS
	Any Amiga® (compatible) computer with at least OS2.04.

DESCRIPTION
	port-handler v41 replaces the original l:port-handler that manages
	the AmigaDOS devices SERx:, PAR: and PRT:. In opposite to the original
	handler my version allows you to create new dos devices that can
	manage the ports of an i/o-board (pre v41 port-handlers didn't support
	third-party parallel.devices). The following mountlist entry illustrates
	how to create a new device called HPAR: that accesses hyperPAR.device 
	(HyperCOM io-boards by VMC) for reading and writing.

	HPAR:
	EHandler = L:port-handler
	Stacksize = 1024
	Priority = 5
	Device = hyperPAR.device
	Unit = 0
	Flags = 0
	Baud = 0 
	#

	You must set Baud to 0 for parallel.devices because Mount always tells
	port-handler to use a baudrate of 1200 when Baud is not specified!
	Because of this port-handler thinks that it talks to a serial.device.

INSTALLATION
	All you need is to copy the files "port-handler" and "_port-handler" to
	your "L:" drawer.

SPECIAL THANKS GO TO
	Stephan Riedelbeck for testing port-handler on his system and debugging.
	Jens Gerrit Schröder for giving me the idea of rewriting the handler.
