Did you try a cable, wired as shown, with a DB9 <-> DB25 adapter?  I think
all the signals involved are there ion teh DB9.  I'm tryng to remember
whether I was using HW or SW handshaking on mine, but I can't, it was
several years ago.  I do know I was using specially wired serial cables.

Yep, worked like a champ.  Set teh plot speed down to 1-2" per second and
have a beer while it plots.  See my other message about this -- I hacked
up an HP pen body to adapt a .5mm fine-tip permanent marker to the
plotter.  Also, we could not get the paper carriage to hold the PCB
material well enough for good positioning, we had to tape it to paper.
