Would you like a few "RS232 Smart Cable"s?
I've always been curious as to exactly what these contain, and what th
eswtiches set. Any clues?
They obviously do not work anywhere near as well as a conscious human
being with an LED tester and a breakout box.
I think it's always the case that a clueful person armed with test gear
will beat a simple 'automatic' device...
