Byte Swap
Specifies if and how the order of bytes in data received and
sent is to be rearranged. Different manufacturers store and
transmit multi-byte data in different combinations. You can use
this parameter when dealing with floating-point or other multi-
byte values, as there is no standard method of storing these
data types. You can set this parameter to rearrange the byte
order of data received or sent into an order more useful or
convenient for other applications.
