Well, then you get into a argument.  What do you mean by "vt100"?  Apparently,
a real, live, standard DEC VT100 terminal did not support the block mode
sequence I talked about in my article, but one version of the DEC VT100 did,
and pretty much every VT100 clone did as well, and the real DEC VT102 I had
also supported it.  Using block mode is not the only to get the terminal to
send something, of course.
