Hmm. Not in *my* copy of the VT100 User Guide. It does mention the
"ESC [ ... q" escape sequence which turns on any of the four status
LEDs or turns them all off, with parameter values of 1, 2, 3, 4 or 0.
But on VT100s and most clones, ^Z just prints a blot on the screen.
Every decent VT100 clone I have seen supports at least one status LED
and usually all four.
