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

[Hittner, David T (IS)]

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.
