Warren, We can take this offline. The quick answer is as far as simh is concerned leave everything as 8 bits. I'll show you how to make the rest work properly. The logins will run 8 bits also, but will run with parity enabled which BSD will handle just peachy.
Also, as I mentioned independently, I very much recommend not using DZs, but using DH's. Most BSD UNIX boxes ran with Able DHDM's because there were both higher performant and cheaper than 2 DZ-11 (the cost of single Able unit got you 16 ports, compared to 8 from DEC, plus they worked better). The DZ were originally developed by DEC as a cost reduced terminal interface to the original DH11 - which was a full system unit on the Unibus and the DM11 (modem control was an option). So they took of a lot of space/power etc. Unfortunately the DZ were CPU hog's (see one of Bill Joy's notes circa 1979-80 - which I probably have somewhere) and sadly the DZ's did not support full modem control (which was always a SW nightmare). I would later get to know some of the folks that made those choices from DEC's HW team (they originally screwed up the original MC-500 serial boards also but that's another story). Anyway, int he late 1970's Able's Ken O cloned/enhanced the DH and DM into a single hex board and since the UNIX community was often university folk, driven by cost (and the DHDM [Able's product] plus did flow control in HW) they were the gold standard for UUCP, particularly with Trailblazer et al. As I said, we can take this off line, and I'll help you.
