Presentation

[Jordi]

First of all, let me introduce myself. My name is Jordi and I'm not a 
programmer. I'm just a psychologist interested in programming since 
HyperCard. Neither my programming knowledge nor my english are not as 
they should be, so I hope you could understand me.
I am trying to make a presentation software to present visual and 
auditory stimuli and to send marks to a electrocardiogram recorder 
(BIOPAC System). I know runRev can 'write to file "LPT1:"' but BIOPAC 
waits for a TTL pulse. I don't know where is the lost link. How could I 
send a code trough the paralel port in a pulse form? Anybody can help 
me in this topic?

Thanks in advance. I hope to learn a lot in this list.
