Flow Control with Timeout: The scanner asserts RTS when it has data to send and
waits for a delay (see RS232 Timeout on page 37) for CTS to be asserted by the
host. If the delay time expires and CTS is not asserted, the device transmit buffer is
cleared and scanning may resume. Default = RTS/CTS Off.
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 time-
out by scanning the bar code below, then setting the timeout (from 1-5100 milli-
seconds) by scanning digits from the Programming Chart, beginning on page 309,
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.
