DATALOGIC PROPRIETARY INFORMATIONS
The module returns in RX state after transmitting all the bytes of the packet.

IDLE mode
In order to maximize battery duration on portable devices a low-consumption state is used.
In this state with IDLE/RX_ pin asserted, all hardware blocks swith to power-down mode or switched off.
To wake up the module, the host must deasserted IDLE/RX pin (Set RTS). In IDLE mode CD# has low level
(shown in fig. 3).

COMMAND mode
When the host puts the module in RX mode and then sends the escape string [ESC]#+CMD[CR],
COMMAND mode is entered.
To confirm COMMAND mode, STAR-Module answers to the host the string [STX][CR] using TX_DATA pin.
In this state normal functioning is disabled, but it is possible to send configuration commands to the module,
in order to change the settings loaded on its configuration EEPROM.
Command must be sent using RX_DATA pin @38400, N, 8, 1 in the form: [ESC]xxxx[CR].
While answers from the module are in the form: [STX]xxx[CR].
If an incorrect command is sent, the answer is: [STX][NAK][CR].
In Command mode CD# has low level.
The state is exited using the exit command: [ESC]FF[CR] causing the reset of the module and activating the
new configuration saved on EEPROM.
NOTE: commands are case sensitive.
