FWIW, A dated comment from someone at Digital indicating that Ultrix 4.3 treats
DELQA and DELQA-Plus as DEQNA, and it is unlikely to ever change.

I also see other posts showing Ultrix 4.5 also running in DEQNA-LOCK mode.
Maybe Ultrix was never upgraded to use the DELQA and DELQA-Plus enhancements.
Well, as others pointed out, the normal operation/programming of the
DEQNA and DELQA are the same.
The DELQA-PLUS is a different story. But that's not what we're dealing
with here.
So, it really works pretty much the same no matter if it is a DEQNA or
DELQA. The differences have more to do with some built-in MOP handling
in the DELQA, along with the ability to perform network booting, which
the DEQNA cannot. Also some watchdog functionality.
So yes, I would indeed expect that Ultrix would treat the DEQNA and
DELQA the same. And if it don't have a driver for the DELQA-PLUS, it can
run that one in normal DELQA mode as well. The DELQA-PLUS mode is
better/more efficient, but that is the only one with a different
programming model.

Cory, could you post the output from showing the device in simh?
I wonder if there might be some confusion about how to turn off lock
mode. I've never even tried modifying that. By default, I would
assume it would be correctly configured, meaning it should work
right if you don't try to "fix it".
I am doing SET DEQNALOCK to OFF, and SHOW XQ (in my initial posting
shows that IIRC) with it in DELQA mode, and later on after probing
and initialising it, despite DEQNALOCK set to OFF and showing as OFF,
SHOW XQ shows it has reverted to being in DEQNA mode.
No. You initial posting showed the dmesg output, but not the simh
input or output, unless I'm very confused.
