I wrote a mostly-working Mathematica frontend once that used Xterm's
split-personality 4014 and VT100 modes; unlike the fairly crappy X-windows
Mathematica (which wasn't a normal frontend like the PC or Mac versions)
it talked to the "math server", handled notebooks (well, tried to, anyway)
and so forth.  I don't know if it would have worked on a VT340 -- we didn't
have any to try it with!  We did have some very nice VT100/4014/X-Terminal
widgets (which began life as VT100/4014 emulators but grew X support by
way of a new ROM several years after we bought them -- neat!) but my
program did *not* work on them; they couldn't be flipped between 340 and
4014 mode without user intervention, or perhaps it was that they cleared
the screen; I don't recall.

  foolish and bewildered and astray: can any man?
