it is a the same pinout as a pc so if you got nothing on the console with a rollover cable then you may well have a bad port... the console speed defaults to 19200k lots of sensible people set them to 9600...
swapping power supplies is a worthwhile test but since you have a multimelter you've probably tested the ps already.
