outgrowth of those protocols?
Typically seen with half-duplex implementations, like "Over" in
two-way radio. Still used in TTY/TDD as "GA".
DId that ever actually occur over the internet such that telnet would
need it? Half duplex seems to be pretty clearly an L1/L2 problem. IIRC,
it was something of a pain to implement.
