ATOMIC QR-CODE READER - Documentation - Trigger in Host Mode

[exouser]

Hi all,
in the documentation AtomicQR_Reader_EN.pdf at page nr 7, is described a trigger mode, its named an HOST-MODE that, if i've correctly understood, activate a software triggered reading method.
Anyone knows commands to send to the reader to start/stop reading barcodes via serial port?

Any help will highly appreciated , thanks in advance.
