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 Programming Chart, 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.
