The context I had in mind for this kind of usage was communicating with an EEG system when specific stimuli are presented, or when participants respond. This is typically how event markers are put in EEG experimental protocols, from what I understand.

You will find this covered in the "How to Present TTL Signals Through the Parallel Port", "How to Use the Parallel Port Monitor Tool" topics in the documentation's "How To"-section as well as the language reference topics for the <port> element.
