[GreenKeys] RS-232 to Polar Relay

[Tom Hunter]

John,

A while back someone (and I cannot remember whom, because he deserves the
credit.) Mentioned that a polar relay can be driven directly by an RS-232
output. Think about it, it is really a polar signal.

I am kicking myself because I never thought of something so obvious.
