I now have a little time to work on my parport driver for the ATEN
parallel port switch.
My first attempt at the switch mostly involved me rewriting portions of
the lp driver to use the switch. What I would like to do this time is
write it closer to the new daisy chaining idea of 1284.3. Since this
switch doesn't do 1284.3, it is pretty much useless for anything other
than printing though.
Where is the best place to start? I started looking at daisy.c in
linux/drivers/parport. I'm not clear on how to emulate a parallel port
so that I don't really touch the data going to the printer, just pass it
through to the port itself.
One of the other things I accomplished that I thought was pretty cool, was
that I was able to get multiple printers going simultaneously. Is this
something possible to do with the 1284.3 drivers? I am guessing that I
will have to muck with the data if I do this.
