I am looking for an IBM (compatible) interface that I want to use in a special
project. I am not very good (read bad) in IBM hardware , especially interfaces
and I would really appreciate if anybody could help me with that.

As I said , I am looking for an interface that would allow me to close or
open a circuit (external circuit) by means of sending a certain value to a
memory port. This means that I would like the interface to have some kind of
switch or something similar so that when I use that certain port , I would 
have the switch to be closed or open.

If there are no such interfaces , then could anybody tell me how could I do
this using the COM or LPT port (if this is possible).

Again , I would be really grateful if somebody could post this for me here
or mail me any information regarding this subject (such as price and a few
technical characteristics) to 

           vohaul@choate.edu

Thank you.
