Use the MAC address to select the desired scanner to communicate
This command is useful when multiple scanners are connected to the SmartCradle in PICO mode.
Select By MAC is often preceded by a Get Connected MAC command to provide a list from which
the desired scanner will be selected. Afterwards, all the subsequent serial command will be send to
this selected scanner, and the other scanners will not be able to communicate with the host until a
Deselect By MAC command is sent.
