I have been working on a parallel port project from Oct 2002, I think I'm starting to urinate SuperIO documentation! I'll let you struggle, but I can tell you the code I sent is about as bare min as you can get when you want to get to the bit level of the parallel port -in user space-. You can outb(2) if you want to setperm() or run as root. -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org, Minnesota, Linux | Fax : (952)943-8500 Key fingerprint = AB15 0BDF BCDE 4369 5B42 1973 7CF1 A709 2CC1 B288 _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
