Event markers

[David McFarlane]

Tim,

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
really does like to take any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they strive 
to respond to all requests in 24-48 hours -- this is pretty much their 
substitute for proper documentation, so make full use of it.  3) If you 
do get an answer from PST Web Support, please extend the courtesy of 
posting their reply back here for the sake of others.

That said, here is my take ...

OK, let me get this straight.  You have one computer running E-Prime, 
and another computer running VPm to collect physiological data.  You 
wrote a perfectly good program in E-Prime to send signals from the EP PC 
to the VPm PC.  But instead of simply running your system to see if it 
works, you ask us if it will work?  What am I missing?
