Handshaking

Hardware Handshaking

Review your system documentation to identify handshaking require- ments, and use these labels to change the settings if required. The following brief descriptions explain each selection.

CTS/RTS Flow Control - is hardware handshaking. The scanner activates 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 characters for no more than 2ms1.
