 		 #148984 - ... plus the infinite variations...
Responding to: ???'s previous message
... on handshake signals presence/absence; surprising power levels present on unexpected pins (e.g. pin 9 = RI a.k.a. "nobody-knows-what-this-signal-is-good-for"); PCB designer using the wrong (= mirrored) footprint; 5V and "inverted 5V" levels (a.k.a. "this is good enough"), 56000 Baud instead of 57600 (a.k.a. "this is close enough") etc.etc.etc.... :-)
