To freeze a listing that was scrolling by on their terminal, they'd
!quick! roll the switch to 0 baud or something, then !quick! roll it

What a kludge compared to Xon/Xoff ^S ^Q that decent terminals like
the VT52/VT100 used. :-)
I used to use a VT50 with a rotary baud switch on the front.
Never tried that trick, however (I think ^S/^Q worked fine
with NorthStar BASIC on the IMSAI I had it connected to).
