[Elecraft] Long RS232 Runs - RS422

[Michael Walker]

I agree with Jim.

I have pushed long runs of RS232 at lower baud rates (4800) out to about
1000' for some temporary commercial applications.

Some of us just try it and see if it works, and others want to do what is
know to work.

Me, I'm a just try it type of person.
