remote plotting

[gt3930c at prism.gatech.EDU]

 	I was hoping someone out there might be able to help me with
a small problem. We have access to a number of machines, but only one
has an hpgl plotter attached to it ( the plotter is /dev/ttyd3). Is there
some way we could access it from other machines? I was thinking along the
lines of some mail type server, where you would send mail to plotter at ...
and if there is something in /usr/mail/plotter the file gets plotted.
Any help solving this problem would be appreciated.
