Are you claiming that it's impossible to have a
modem where there are
9600 transitions/second on the 'line' side? Because if so, I don't
believe you.
I'm claiming that it's not possible to have a 9600 baud modem on a POTS
line. Obviously it is possible on other transmission lines or media with
greater bandwidth.
What was the official use of this stick? Some kind of
packing/transit
clamping device?
Yes.
