There is absolutely nothing 'odd' about the '7 wire', it is _the_ standard
for bi-directional hardware flow control, in common usage for at least 25
years that I'm aware of.

Humm, src code snooping time I guess, when I get a chance. Right now its
a race against time to get us on the air with a fresher transmitter since
I can no longer get 4-1000 tubes to service our old GE, and the ones in
it are on their last month. So I'm outta here in a few minutes to go see
if I can do a decent job of cutting 3.125" transmission lines on a 12"
chop saw with a carbide blade.
