Flow control
•
None
Your computer and scanner only use TxD
and RxD signals for communication. No
hardware or software flow control is used.
•
RTS/CTS
It is hardware flow control. If your scanner
is ready to send bar code data to your
computer, it sends an RTS signal, and waits
to receive a CTS signal from your
computer. If your scanner doesn’t receive a
CTS after a timeout, you’ll hear five
warning beeps from it.
•
Xon/Xoff
It is software flow control. When your
computer is unable to receive data, it sends
an Xoff signal to notify your scanner to
stop sending data; it sends an Xon signal
when it’s ready.
•
ACK/NAK
Your scanner sends data after it received an
ACK signal from your computer, and will
resend data if it receives an NAK signal.
Inter-character delay
It determines how fast your computer receives
each character and displays it on the screen. If
the speed is set too fast and your computer
system is slow, your computer may lose data.
