- 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.
