I tried using a DHV11 board in my microvax II a few months ago under
version 1.2G and had trouble. I edited the /etc/ttys file and signal'ed
init and then I could log in fine over the DHV11. Then I shut the unit
down and re-booted and when the machine came up, I kept getting some error
message on any serial line I hooked up to so I could not log in with a
serial port, not even the console! I had to telnet into the machine and
disable the dhv11 and re-boot. 
Sorry that I can't be more specific about the error message,
I think it was something about getty timing out or something. I mentioned
it to someone and it seemed to be a known problem. If this has been fixed,
I would like to know.
