Can VAX with 4.3Bsd UNIX support Data General 605x terminals?

[Robotics]

The robotics group at Harvard University has a Data General MV/10000 with a
number of DG's Dasher 210 and 460 terminals.  We would like to make a VAX
780 running 4.3Bsd UNIX treat them properly.  Apparently, specifying
terminal type 'Mg' to tset is not good enough -- backspace (^H) is still
being sent by VAX which makes DG terminals send cursor home (top left).
There are also other, more subtle problems.  If you have any advice to
offer, please respond to: robotics at harvard.ARPA  -- thanks.
