Addressing
1.
The ATHA command can be used to check the MAC address of device
itself. When argument is used, it is used to set the destination MAC
address. (FF-FF-FF-FF-FF-FF means broadcasting). The total length if
17 includes the delimiter’-‘.
2.
Description of serial number: the serial number used in ATSN
command consists of 32 bits. The upper 16 bits are domain address,
while the lower 16 bits are node address. The definition of DN is
same as that of SN, but DN has only domain address portion. If the
MAC address of source device is a broadcast address and the DA
portion of the source DN matches DA portion of destination SN, they
can communicate.
