Command sequence for decoding
• The host device sends a start decoding command to the device ‑ for single decode or for continuous
decoding
• The device sends the corresponding acknowledgement back to the host device.
• The barcode decoder takes over and sends the barcode result to the host device. The barcode result is
sent in clear ASCII text, that is, without the framing protocol.
• The host device sends a stop decoding command to the device.
• The device sends the corresponding acknowledgement back to the host device.
