I've already written half the program in visual basic. It reads the hpgl
file, draws it on the screen, then it will probably send to the plotter,
serially, a group of bytes stating the hpgl commands. I've got to get the
mechanics finished first before doing the electronics. It's dc motor driven
with encoder position feedback.

Are you using a custom written driver to interface directly to like
AutoCAD or something, or are you using one of the available packages out
there that translate a standard file into the proper control signals for
your machine?
