We hooked an A/D and a D/A to the same printer port on a 286 last
year.  There is a place in memory (don't ask me anymore) that gives
the address of the memory controlling the pins to lpt1,2,etc.  We
just used ML to write directly to the pins, and read directly back
from them.  There are just enough pins for input and output, that you
can drive both.  We had nothing left over.
