Actually, the greatest objection was that these sequences were way too long,
and that a binary format would be much shorter leading to a lower overhead
design (even at 1200 baud, which was pretty good for some areas, the X3.64
output generated quite a lot of annoying pauses), plus (as noted) be easier
to implement.

(I thought a sequence based on the Lear Seigler cursor motion code would make
 more sense, myself)

All water under the bridge, just note that OSI isn't the first over-
engineered protocol out there...
