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. Sander
