+// a 550 usec pulse / 2000 usec space between the address and the command.
+// Here are the fine details:
+// A "zero" is encoded with a 550 usec pulse, 450 usec space.
+// A "one" is encoded with a 550 usec pulse, and 1450 usec space.
+// The header is a 8000 usec pulse, 4000 usec space.
+// There is a mid-way marker of 550 usec pulse, 2000 usec space.
+// The pulse train ends with a trailing 550 usec pulse.
+// The entire train is resent for repeats.
+// Each command runs for 60000 usec before another can be executed.
+// The carrier frequency is 38 kHz.
