port-handler v41.3
COPYRIGHT AND DISCLAIMER
port-handler v41 is copyrighted 1998/99 by Stephan Rupprecht. All

required. Redistribution allowed if the package is left unchanged.
The author is not responsible for any damage caused by the use or

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
#
Please note the 'Baud' field which must be set to 0 for parallel
devices!
INSTALLATION
All you need is to copy the file "port-handler" to your "L:" drawer.
PROBLEMS
Mount v40 and later crashs if you try to mount a EHandler twice!
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.
Thomas Richter for his help with the BCPL magic.
HISTORY
41.0 first public release
41.1 port-handler is a single file now. Thanks to Th. Richter for his
help.
41.2 Compiled/Optimized with GNUC. included dosdrivers for all HyperCOM
boards.
41.2a No changes, just added some new dosdrivers for the ioblix board by
RBM.
41.3 reduced filesize a bit :) A warning about mount v40+ has been
added to the doc. prt:raw didn't work, baud rate and control
information following the device name were ignored (eg. ser:9600/8n1).
