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.
