Basic format for control data
The transmission of control data from the computer
starts with a STX signal, followed by the command,
the parameters, and lastly an ETX signal in that
order. If there are no parameters, then the
parameter signal does not need to be sent.
Note:
If multiple commands are transmitted, be sure to
wait for the response for the first command to come
from this unit before sending the next command.
