Sometimes I had only lunch hour to do PMs, and one office worker always
ate into my time because she had to 'finish something'.
Pretty soon I found that <esc> [ 2 ; 9 y would put all ANSI terminals
into continuous self-test, and that solved the problem:-)
Those were the days!
cheers,

The 1052 Selectric console on the 360's were not on a channel, but
driven via direct I/O directly from the CPU microcode. (Yes, the

channel, but it actually wasn't.)
One prank to pull on an operator was to write a CCW chain to ring the
1052 bell and then to a TIC back to the bell ring CCW.
At least on DOS/360, pretty much impossible to kill without doing an
IPL, as the keyboard would be locked.
Fun from my younger days.
