Telnet sessions where often initiated from half duplex terminals. Pushing that flow control across the network helped those users. -- Mark Andrews

When I wrote my first implementation of telnet ages ago, i was both amused and annoyed about the go-ahead option. Obviously patterned after audio meat-space protocols, but I was never convinced it wasn't a solution in search of a problem. I wonder if CDMA was really an 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.
