This really isn't a Python question -- it's a low-level hardware question.  
The short answer, however, is that it's almost certainly impossible to 
anything like what you want, for a number of reasons.  The output pins on 
the connector are driven directly by some sort of serial hardware driver, 
and the hardware almost certainly doesn't expose an interface which lets 
you do what you're after.

I think want you want to be doing is looking at using a parallel port 
(commonly called a printer port on PC's).  But in any case, the answer to 
"How do I make the parallel port do this?" is a low-level hardware 
question, not a Python question.
