Byte Order
The 16-bit values documented here store the most significant byte first. This is called Big Endian format.
For example, a hexadecimal value of 1235H is stored with 12H in byte 0 and 23H in byte 1.
If your receiving system is not a Big Endian CPU (Intel processors are not), then you will have to swap
the byte order before you can use the value. If you don't swap the bytes, then a value of 1 from the router
will be interpreted as 256, 2 as 512, and 640 as 32770.
