+	 *    Then, scanForReply returns the id of the command and the base class
+	 *    can handle time-out and missing replies.
+	 *
+	 *  - Periodic, unrequested replies. These are replies that, once enabled,
+	 *    are sent by the device on its own in a defined interval.
+	 *    In this case, the id of the reply or a placeholder id should be added

+	 *    From then on, the base class handles the reception.
+	 *    Then, scanForReply returns the id of the reply or the placeholder id
+	 *    and the base class will take care of checking that all replies are
+	 *    received and the interval is correct.

+ * Helper class to convert variables or bitstreams between machine
+ * endian and either big or little endian.
+ * Machine endian is the endianness used by the machine running the
+ * program and is one of big or little endian. As this is portable
+ * code, it is not known at coding time which it is. At compile time
+ * it is however, which is why this is implemented using compiler
+ * macros and translates to a copy operation at runtime.
+ *
+ * This changes the layout of multi-byte variables in the machine's
+ * memory. In most cases, you should not need to use this class.
+ * Probably what you are looking for is the SerializeAdapter.
+ * If you still decide you need this class, please read and understand
+ * the code first.
+ *
+ * The order of the individual bytes of the multi-byte variable is
+ * reversed, the byte at the highest address is moved to the lowest
+ * address and vice versa, same for the bytes in between.
+ *
+ * Note that the conversion is also its inversion, that is converting
+ * from machine to a specified endianness is the same operation as
+ * converting from specified to machine (I looked it up, mathematicians
+ * would call it an involution):
+ *
+ * X == convertBigEndian(convertBigEndian(X))
+ *
+ * Thus, there is only one function supplied to do the conversion.
