Some 2-way

radios we used in broadcasting had timers that shut them down after 5

wouldn't be a bad idea either.


Most programmable communications transceivers have a timeout feature
(with selectable delay). Really helps in stuck mike situations (and
pulls the rug out from under long-winded people, too). All 2-way
transmitters should be so equipped.

The guys who designed the original EtherNet anticipated this problem and
built an "anti-jabber" circuit to every node.
