Members
| Member name | Description | |
|---|---|---|
| None | No control is used for the handshake. | |
| XOnXOff | The XON/XOFF software control protocol is used. The XOFF control is sent to stop the transmission of data. The XON control is sent to resume the transmission. These software controls are used instead of Request to Send (RTS) and Clear to Send (CTS) hardware controls. | |
| RequestToSend | Request-to-Send (RTS) hardware flow control is used. RTS signals that data is available for transmission. If the input buffer becomes full, the RTS line will be set to false. The RTS line will be set to true when more room becomes available in the input buffer. |
Remarks
This enumeration is used with the Handshake property.
