You may be stuck writing them yourself, as the equipment is no longer
supported by Huntron. They do have some DOS programs that you
might be able to use via "System Exec" though. Could be worth a
shot.
Do you have manuals for the units describing any commands (i.e. a programmer's manual)? This would go a long ways to making writing drivers a doable task.
