    You are right in that the reguler parallel device does not work when
trying to talk to a device other then a printer.  The normal parallel.device
want to receive paerout, and other standared printer port signals.  The only
way to acces the port directly is to talk to the CIA ( complex interface
adapter chips ) whic the amiga uses.  I have had no succes myself yet in
talking to these chips.  However you might have better luck.  You will need
the ROM-KERNEL manual which has a brief chunk of code in assembly that is
supposed to acces the cia chips.  Also there is some source code on a fred
fish disk ( I dont remeber whic number) that contains the assebmly source to
acces the chips.  However when I use the assebler that comes with lattice-c to
assemble the code it dose not work.
