Table 14 defines the command data types used in the commands.

The mote command interface provides a way to send and receive network packets, access local configuration and diagnostics, 
and receive time stamps. All packets between the microprocessor and the mote are encapsulated in the HDLC format 
(RFC 1662) and have the following structure (see Figure 11). 

The command type indicates which API message is contained in the message content. The message content for each command 
type is described within the following sections.

FCS is calculated based on 16-bit FCS computation method (RFC 1662). The mote checks the FCS and drops packets that 
have FCS errors. There is no mechanism for the mote to tell the microprocessor that a packet has been discarded, so the 
applications layer must implement reliable delivery, if desired. All numerical fields in a packet are in big endian order (MSB 
first), unless otherwise noted. Section 7.4.5 provides an example of HDLC packet construction and HDLC packet decoding.

Table 15 provides a summary of mote commands, which are described in detail in the following sections. For error handling, 
all other packet types should be ignored. The Destination column indicates whether the packet is sent (or received) through the 
network or processed locally by the mote.
