a change in state. In conjunction with Packet

identifies the receiver and may present status messages. The machine ID can be used 
by equipment communicating with the receiver to determine the type of receiver to 
which the equipment is connected. Then the interpretation and use of packets can be 
adjusted accordingly.
The status codes are encoded into individual bits within the bytes. The bit positions 
and their meanings are listed in the table below.
