The error you're getting is indicative of a low-level parallel port communication error. You should figure out what address your parport is at; you can do this by loading the linux parport and parport_pc drivers and seeing what they say. Also check your cables. I know i sound like a broken record regarding EPP cables, but it really is the problem 99% of the time. -- Sebastian Kuzminsky sudden wind it stole my hat and i went on chasing it -- Gogol Bordello ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
