    I'm wonder if i can use lines INTR & WAIT of parallel port in EPP mode
    as controlled inputs. Three other lines are user defined so there is
    no problem. Especially i'm intresting about INTR line. This is
    interrupt signal so i'm not sure if changes on this line causes same
    changes on data lines. I want to use date lines as independent
    outputs. So my question is, if this two lines are fully programmable
    by user ??
