2. <command>: “AQ” - Acquire remote control of the device and lock front panel
key pad; no arguments
When acquired, the reader will be in the Remote Control mode. The
LCD will display Remote Control mode, and the printer will automat-
ically be deactivated. The reader will stay in the remote control mode
until the release (RL) command is received or the STOP button on the
front panel is pressed.
