+// Define constants and variables for buffering incoming serial data.  We're
+// using a ring buffer (I think), in which head is the index of the location
+// to which to write the next incoming character and tail is the index of the
+// location from which to read.
+// NOTE: a "power of 2" buffer size is recommended to dramatically
+//       optimize all the modulo operations for ring buffers.
+// WARNING: When buffer sizes are increased to > 256, the buffer index
+// variables are automatically increased in size, but the extra
+// atomicity guards needed for that are not implemented. This will
+// often work, but occasionally a race condition can occur that makes
+// Serial behave erratically. See https://github.com/arduino/Arduino/issues/2405
