When using a control system program instead of terminal program, all lines output from the display are
preceded by a carriage return character (<CR>) and line feed character (<LF>) and then followed by a
carriage return character (<CR>) and line feed character (<LF>), as shown in the example below. Refer to an
ASCIItable for more information about character codes if needed.
>set volume=0<CR>

Commands and responses
To access display information or to adjust display settings using the room control system, send a command
after the command prompt (>), send a carriage return character or press ENTER, and then wait for the
response from the display. Responses are preceded by a carriage return character (<CR>) and line feed
character (<LF>) and then followed by a carriage return character (<CR>) and line feed character (<LF>). If no
command prompt is present, send a carriage return character to thedisplay. If the display is ready to receive
commands, it will show a command prompt (>) when the carriage return is received. See the example below.

>get volume
volume=55
>
In the example below, the user used =-50 instead of -50.
