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

[Scott]

I'm trying to get Task Events to work for responses as well as for stimulus 
onsets and offsets. I have a program that reliably uses Task Events to send 
a WriteByte to the parallel port for each onset I choose. However, I'm 
having trouble marking the time of each response. So far, I've tried Target.
Keyboard.Press, Target.Keyboard.MaxCountReached (when MaxCount=1), and 
Target.Keyboard.TimeLimitReached. The last one works every time, but only 
when no response occurs during the response duration, as I expected.  
Obviously that does not help mark a response. Press and MaxcountReached 
actually does work for me sometimes, but only occasionally (which seems 
odd), and I can't see any pattern to when it does and does not work. Note 
that each onset event is followed by an event that write a 0 with a 20 msdelay.Also, I send 
a code that's depends on the accuracy of the response about 300 ms after 
end of the response time limit using WritePort. This also works rereliably, 
on every trial. However, these codes are only sometimes preceded by a code 
generated at the time of the response by a Keyboard event; I expect that to 
happen every time there has been a response.

I have sent PST a support request, with my program, data, and event codes.This is a followup to 
PST's response to my request for clarification about the meaning of each of 
these Keyboard events. I am trying to apply what they explained, without 
success.

Has anyone managed to get any of the Keyboard events to reliably send a 
WriteByte for at the time of each response in their program? I want to be 
assured that at least one of these Keyboard can work reliably.

Thanks!
