Rs232 Timeout; Xon/Xoff; Ack/Nak - Honeywell Vuquest 3320g User Manual

RS232 Timeout

When using Flow Control with Timeout, you must program the length of the delay
you want to wait for CTS from the host. Set the length (in milliseconds) for a
timeout by scanning the barcode below, then setting the timeout (from 1-5100
milliseconds) by scanning digits from the
222, then scanning Save.

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

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
