Packet Format

To distinguish the remote command from the remote command control
message containing it, we will often refer to the remote command control
message as the RC control message. Figure 10.1 shows a data frame
containing a remote command control packet in four layers:
Fields of the remote command sent to be stored at the remote station
(application layer).
Fields of the RC control message containing the remote command
(application layer).
The message header fields common to all remote command control
messages.
The fields common to all message transmissions in the Native mode.
