TwclSerialRtsControl Enumeration

Specifies the RTS (request-to-send) input flow control.

type
 TwclSerialRtsControl = (
 rtsControlDisable,
 rtsControlEnable,
 rtsControlHandshake,
 rtsControlToggle
 );

The TwclSerialRtsControl type exposes the following members.

	Name	Description
	rtsControlDisable	Lowers the RTS line when the device is opened. The application can use `EscapeCommFunction` to change the state of the line.
	rtsControlEnable	Raises the RTS line when the device is opened. The application can use `EscapeCommFunction` to change the state of the line.
	rtsControlHandshake	Enables RTS flow-control handshaking. The driver raises the RTS line, enabling the DCE to send, when the input buffer has enough room to receive data. The driver lowers the RTS line, preventing the DCE to send, when the input buffer does not have enough room to receive data. If this value is used, it is an error for the application to adjust the line with `EscapeCommFunction`.
	rtsControlToggle	Specifies that the RTS line will be high if bytes are available for transmission. After all buffered bytes have been sent, the RTS line will be low. If this value is set, it would be an error for an application to adjust the line with `EscapeCommFunction`.
