Exceptions
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.
The stream is closed. This can occur because the Open() method has not been called or the Close() method has been called.

This method is equivalent to the following Visual Basic code: MSComm1.OutBufferCount = 0
. It clears the transmit buffer, but does not affect the receive buffer.
