A *real* D210 has an ANSI mode, settable by either dip switch, or an
escape sequence.  I'm not sure about the D411, I never saw one.

Anyway, I once was forced to use a D210 on an Onyx C8002 (Unix System III).
Seems that the ANSI mode is very close to generic vt100, as far as a
termcap entry goes.  I fashioned a d210 termcap by using a vt100 as a
guide.  But, the D210 has no backspace key! (DG uses DEL as backspace)
So, with a little trickery, I used a line like the following to change
the stty modes in my .login:

    if ( $TERM == "d210" ) then stty erase '^?' kill '^a'

Since I was using the DEL key for backspace, I chose CTRL-A for Delete.
I seem to recall having to do something else during the login sequence,
but I can't remember it now.  I no longer have access to the Onyx
so I'm afraid I can't go look it up and post it.  Sigh.
