I think Michael is on the right track here.  We have several D210, D460
and D460+ terminals here, and there is a DIP switch on the back of the
terminal that causes it to recognize and act on ANSI control codes.  
Unfortunately, "vi" and "emacs" didn't work very well when I tried to
use the terminal as a vt100, although it may be the case that with a 
little terminfo hacking they could be made to work.
