I have to add a parallel footpedal device to my system and
can't find much parallel documentation in IBM Xenix 2. The
device comes with its' own card. My questions are:
* is it possible to talk to it using only an application program
(no driver)? Has anyone had luck doing this with the memory device?
* can the parallel driver already in the system be used to talk
to another device simply by changing the interrupt vector
in the master file?
* does anyone have a parallel driver source in the public domain?
* in the current IBM Xenix is it possible to do such things as
nonblocking I/O with the parallel driver?
* any other suggestions are appreciated
thanks
