hey everyone- I am looking for a way to use a closure to trigger an event in a program running on my BSD box. Let me clarify, I want to be able to use a switch or other electrical closure, attached to the computer in some way (I know it can be done with the parallel port) and use it to trigger events- I.E. when you get a certain closure, send "x" data out the serial port, when you get another closure send "y" data out the serial port. Can anyone point me in a direction on how to go about implementing such a program and what code to use to get the information from the ports. I am willing to add a GPI card or the like to the system if need be, but I would rather not have to ad such an expensive device into the system. Thanks for all of your help!
