Is anyone using Task Events to signal a response via the Parallel Port?

[Scott]

No one has replied to my initial post here, so I assume no one cares about 
using Task Events for responses. I don't recommend it. I'm giving up on 
this topic with this observation: Keyboard task events don't work in my 
tests the way I expected or the way PST support told me they should. 
Support still has not replied and explained.
