Actually, a real DEC VT-100 can emulate a VT-52, either by being
set up to do so when powered on, or upon receipt of the appropriate
escape sequence.  The binary-vs-ASCII code idea is all wet.
The VT-100 in ANSI mode uses sequences such as ESC [ H to home
the cursor while the VT-52 code is ESC H.  The only place one
could say that "binary" is used for the VT-52 is in its cursor
positioning sequences, which include row and column coordinates
as their numeric value plus an offset (to map them out of the
set of ASCII control codes).  The ANSI sequence for this would
instead use digit characters to spell out the numbers.
