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.
Remarks
This value should normally be set to false, especially for binary transmissions. Setting this property to true can cause unexpected results for UTF32- and UTF16-encoded bytes.
