ACK/NAK

After transmitting data, the scanner waits for an ACK character (hex 06) or a NAK character
(hex 15) response from the host. If ACK is received, the communications cycle is completed
and the scanner looks for more barcodes. If NAK is received, the last set of barcode data is
retransmitted and the scanner waits for ACK/NAK again. Turn on the ACK/NAK protocol by
scanning the ACK/NAK On barcode below. To turn off the protocol, scan ACK/NAK Off.
Default = ACK/NAK Off.
