Concert XR series
Command Structure - Receiving
Command processing begins when the first 0x0D (carriage return) is received.
The Concert XR series will respond, either by making the change specified with
a status update answer code or by replying with an error answer code, within 3
seconds. More commands, however, may be sent before the Concert XR series
responds to the first command. When a command is received, the Concert XR
series echoes the command back in the following format:
<ST><ZN><CC><AC><DL><Data><ETR>
