Please understand that you are probably the first person to try to
use pt with this particular device. That, combined with the
your apparently marginal parallel port makes it very difficult for
any of us to say anything helpful. We just don't know.

"EPP/ECP" usually means "broken". Choose pure EPP if you can.

These are identically the same results that you got on a different
machine (a laptop, perhaps ?) As I explained then, these numbers
are unusual and indicate that the driver is communicating with the
EPAT, but not with the tape drive.

I have an "OnStream" drive that exhibits similar symptoms. I've been
unable to make any progress with it, except to identify it as a "C7"
rev of the adapter - one I hadn't seen before. I'm guessing that
you also have a C7 - and that until we get some specs for it we're
stuck. (There do not appear to be any DOS drivers that can talk
to that adapter.)

I'm sorry that we can't be more helpful right now.
