Hardware Control - PSC QuickScan 6000 Programming Manual

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

Hardware Control

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
than 2msec

CTS Scan Control — is also a hardware control. When scan
control is enabled, label transmission is disabled until CTS is
asserted and de-asserted.
