I have an old XEROX 820-II which I am using for packet radio purposes.
Right now I am using it as a dumb terminal, running SMARTERM, but I
would like to make it more clever.  To do this, I have to know how
to program the I/O port, and possibly how to handle interrupts from
the keyboard.  I would like to use DTR/DTS on the serial port.  I'd
prefer to do it in TURBO Pascal, but assembler is acceptable.  Can
someone tell me how to do this (or does someone have a code fragment
I can look at)?

			Thanks,
