wclSerialDtrControl enum wclSerialDtrControl Specifies the DTR (data-terminal-ready) input flow control. Enumerator dtrControlDisable  Lowers the DTR line when the device is opened. The application can adjust the state of the line with EscapeCommFunction. dtrControlEnable  Raises the DTR line when the device is opened. The application can adjust the state of the line with EscapeCommFunction. dtrControlHandshake  Enables DTR flow-control handshaking. If this value is used, it is an error for the application to adjust the line with EscapeCommFunction.
