SerialPort.DiscardInBuffer Method ()
Discards data from the serial driver's receive buffer.
Assembly: System (in System.dll)
The port is in an invalid state.
- or -
An attempt to set the state of the underlying port failed. For example, the parameters passed from this SerialPort object were invalid.
This method is equivalent to the following Visual Basic code: MSComm1.InBufferCount = 0. It clears the receive buffer, but does not affect the transmit buffer.
