   Hope you have the break out box and cable for it... Several cards I've seen
   for sale on the net are missing them *sigh*

   Might be close, might not.  Spif is a Sun (OEM'd?) card based on an old
   CD180 chip (not cd1800), and has a weird way of handling DTR.  Either way,
   a driver already exists for this in OpenBSD (sys/arch/sparc/dev/spif*).
   Would be easy enough to port it I suspect.  The only thing that doesn't
   work is the parallel port, and that's partly out of laziness on my part.


there are N versions of this hardware.  i've got one that has 2 cd180's on
it (16 serial ports), and no parallel port.  i've been working on a driver
for some time but i never finished all the tty-handling parts.
