Handshaking
CTS/RTS Flow Control - is hardware handshaking. The scanner acti-
vates the RTS (Request to Send) line when it is ready to send data to the
host. The scanner waits for an active Clear to Send (CTS) signal from
the host before transmitting data. If hardware control is disabled, CTS/
RTS communication will not take place. If the host deactivates the CTS
line during data transmission, the host will receive additional charac-
ters for no more than 2ms

asserted as illustrated below.
