Read Value command (RV)
When the “RV” (read value) characters are sent at the beginning of the command the
response returns the value or status and does not execute any action.
RV Command Example
To use the same command to read the ASCII characters “RV” are sent just after the two
start characters “&&” and separated from the “BKL” command with a “,”.
