THINGS TO DO IN THE FUTURE FOR PMOD

* Set up a printer queue system so that multiple pmod sessions can be
  executed that will wait on the previous pmod sesion to complete before
  going on, instead of just saying that the rinter is inaccessible.

* Since not all printers have the same printer codes for desired printing
  modes, add some sort of configurable printer code setup, so the user can
  alter pmod to send any desired codes with any desired agrument options.

* Maybe give pmod a complete Graphical User Interface to give the user
  access to all of the features, including editing of the printer codes and
  options.

* Fix it so that pmod can be made resident without crashing the machine.
  Anybody have any hints on how to write a C program that can be made
  resident, send me some hints, etc., OK?
