LPT port input lines

[Arek]

Hi,

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 ??
