3.9.4 Laser LT Query Display Command
The query display command will return what is currently being displayed and is mainly intended for testing.
An example of a possible operation would be to transmit a weight string or a display message command to the
Laser LT, let it set the display, transmit the query display command and capture the response. The response could
then be compared against what was expected.
