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 millisec-
onds) for a timeout by scanning the bar code below, then setting the time-

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.
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 bar
codes. If NAK is received, the last set of bar code data is retransmitted and
