6-1-1. RS-232 command：
Command format：
This unit uses high-level language commands with a CR (0DH) and LF (0AH) as
the end of the command.
The system would interpret and execute the command only after these two

accepted ! > CR LF：Command correct but execution error (e.g. parameters out

information back to the computer (with CR and LF) and then send the response
string to the computer.
