+Note that APC UPS serial cable part numbers follow a numbering scheme
+where the "940-" prefix identifies them as cables.
+
+	940-1000	straight through cable
+	940-0103	null modem cable
+	940-0020	Basic Signaling Cable (OB and kill power)
+	940-0023	Simple Signaling Cable (OB only)
+	940-LL24	Smart Signaling Cable
+	940-0095	PnP Cable (see Apcupsd manual for diagram)
+	940-0119	Simple Signaling Cable (OB and kill power)
+	940-0127	RJ45-10P10C to USB Cable
+	940-0128	Simple Signaling Cable for Back-UPS CS
+
+"LL" represents the length:
+
+	00	six feet
+	NN	NN feet
+
+The suffix letter represents a minor revision in physical design, or a
+change of OEM, _not_ a change of wiring or pin-out, and all cables
+differing only in this suffix letter are electrically interchangeable.
+Note though the following quote from the APC Discussion Forums:  "At one
+point there were a small number of revision D cables [940-0024D] that
+had some shielding issues from the manufacturer that could maybe cause
+[...] [spontaneous] self-tests)."
