commands from the host device. When RTS/CTS is turned Off, no data flow control is used.
Flow Control, No Timeout
: The scanner asserts RTS when it has data to send, and will wait
indefinitely for CTS to be asserted by the host.
Two-Direction Flow Control
: The scanner asserts RTS when it is OK for the host to transmit.
The host asserts CTS when it is OK for the device to transmit.
Flow Control with Timeout
: The scanner asserts RTS when it has data to send and waits for a
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 timeout by scanning the
barcode below, then setting the timeout (from 1-5100 milliseconds) by scanning digits from
the
beginning on page 313, 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
