Look at the Super Serial Card.  There's a little button with
a big arrow on it.  Grab the button, pull it up, and turn it
until the arrow points 180 degrees from the previous position.

Here's the deal.  One computer must act as DCE and one
as DTE.  You can do this in two ways.  One is to run a
null modem cable with the computer set as DCE.  This
flips the DCE signal to DTE which will result in one
computer having DCE and one having DTE.

However, when you have the Super Serial Card installed,
the Super Serial Card itself is set to DTE (because the
printer is DCE).  So the null modem cable will flip the
signal back to DCE and now both computers have DCE.

With a Super Serial Card set up to output to a printer,
then, you really do not need a null-modem cable.
You can substitute your printer cable for the null
modem cable in your setup and it should work.

If you use the null-modem cable, you must flip the
arrow as described above 180 degrees.  This is the
DCE/DTE switch.

At least I think the above is correct.
