100 feet at 115200 bps through three unshielded
wires, wrapped around a
three-foot-tall Jacob's ladder apparatus enclosed in plexiglass. No bit
errors. We gave up and decided to build a device to simulate bit errors.
What makes you think that wrapped on the outside of a Jacob's ladder has
either the right coupling or the right frequency spectrum to effect a
RS-232 signal?
Well said. It probably had more to do with a burning desire to do
*something* with the giant Jacob's ladder. But we were still suprised when
nothing happened, none of us being hardware guys.
Someone else mentioned a device that you could insert into a serial link
that generated bit errors with a configurable frequency. That seems like the
way to go here, and it can be done with nearly any machine with two
compatible serial ports.
