26 N3680 Decoded Engine User Guide
Flow Control with Timeout: The scan engine asserts RTS when it has data to send
and waits for a delay (see RS232 Timeout on page 26) 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 inside back cover, then scanning Save.
XON/XOFF
Standard ASCII control characters can be used to tell the scan engine 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 scan engine, 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.
