Could be.  Since parity always was rather silly it isn't normally used; I'm surprised DEC didn't delete it from Ultrix the way they did for all the other operating systems.

If you have a real terminal you can configure it for 7 bits and the matching parity, but terminal emulators may not have that ability.  In any case, for that the simh command for 7 bit terminal output is a simple fix.
