CTS/RTS Flow Control — is hardware handshaking. The
scanner activates the RTS (Ready 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 trans-
mission, the host will receive additional characters for no more
1
than 2msec .
