To use it more securely, it is recommended to readout the local serial ID code with
TID command and pad it (either all or a part of it) in the transmitting packet.
When no packet is received, “All Zero” is displayed as the result of this command
execution.
The serial ID code is no relation with ID code setting of REG04 and 05.
Example
>
@ RID CR/LF : requests the received remote station’s serial ID code
< XXXXXXXXXXXX
CR/LF :outputs the received remote station’s serial ID code
