[Simh] EXT :Re: Ultrix 4.0 and DEQNA-LOCK

[Johnny Billquist]

Maybe to vlarify myself. DEQNA-LOCK is not something I would expect 
Ultrix to turn on, and the code Ragge posted certainly reported it 
without appearing to modify it. And it would not make sense to modify it 
before that point, and if it was changed after that point, dmesg should 
not report it.
