It's been claimed in various histories that Mode B was actually a mistake
made in an early keyer, but it was a functional mistake that ops learned to
use. Those operators objected to the fact that the last code element wasn't
automatically sent when expected, so manufacturers like the famous Curtis
who developed the first keyer application-specific integrated circuit (ASIC)
keyer "chip", included both "modes" in their designs.
