Right but for goodness sake, try to make a DH11 work; not a DZ11!!!   Real DZ11'S were SW pigs and consumed a measurable percentage of a vax, particularly when running uucico(8) (they are interrupt crazy).   It is one of the reasons why the Unix community in those days always recommended Able DH/DMs on Vaxen.

We can take this off line.   As I said, it been done a numberof times with simh and the like.   The key is that simh creates a 'serial line' on a TCP port.    You tell UNIX to hang a login off it and then you telnet or whatever to that port.    The older system running in simh, thinks it has a serial line.   It pretty much just works; al biet is slow as hell and chews up a ton of resources.
