Further to Barney's response it should be possible to send switch output via the parallel printer port with the appropriate application ... an example of such an application is at:
http://www.geocities.com/lalimparallel/index.html... however I haven't tested this myself.
Otherwise you are looking at a hardware based solution such as what Barney suggested or as described in the attachments.

Hi all.
Does anyone know if there is a 'standard' way of sending a switch _output_ from a computer? I can't actually think of software that does this, but some must (e.g. RollTalk)... I assume joystick ports are input only, so serial port (or parallel?!)would be the only option?
Don't actually need this yet, but might do, and want to see if someone has a quick answer to save me effort!
Cheers,
Simon
