•RTS — RTS is asserted during transmissions. CTS is ignored.

•RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.

•RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored. XON and XOFF gate transmissions.

•RTS On/CTS — RTS is always asserted. CTS gates transmissions.

•RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates transmissions and controls enable and disable state of scanner.
