Just curiosity, and it might well be a dumb question.  

Say you had physiological equipment attached to the serial port.  The data 
would presumably be available according to the sampling rate of the 
equipment.  How would you know when and how often to 'read'?  Little hardware 
knowledge, so no acronyms or big words in any answer forthcoming please.

Best wishes
