XON/XOFF
Standard ASCII control characters can be used to tell the scanner to start sending
data (XON/XOFF On) or to stop sending data (XON/XOFF Off). When the host
sends the XOFF character (DC3, hex 13) to the scanner, data transmission stops.
To resume transmission, the host sends the XON character (DC1, hex 11). Data
transmission continues where it left off when XOFF was sent.
Default =
XON/XOFF Off
.
XON/XOFF On
* XON/XOFF Off
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 .
ACK/NAK On
* ACK/NAK Off
