though this is mostly about what it looks like from outside the PC, 
rather than programming information.  Also somwhere on the web I found 
datasheets on some NatSemi chips that implement the various parallel port 
modes.  Finally, the only complete documentation on how to program ECP 
mode (including how to probe for what sort of ports you have got) seems 
to be in the Microsoft Developer Network - I couldn't find it on the 
Microsoft web site, but it is on the MSDN CDs.

Could you send them to me in uuencoded format? I looked at the microsoft 
ftp site, but they don't have that information there among the other MSDN 
articles available. www.fapo.com isn't too informative... 

And Alta Vista search for parallel port programming didn't return too 
much information - that the is a thing called parallel port FAQ (the 
maintainer wants information on EPP and ECP aswell), and that there is a 
book in the making about parallel port, it's programming, etc.
