I looked at this, too, but there is no pinout diagrams AT ALL, trying to
get you to knuckle-under and buy the $35 cabling. Also, on other webpages,
there are references to two 9V batteries to power the RS-232C adapter! How
stupid is that?

I guess he shoulda bought another brand.....one that came WITH the cables!
