Exceptions
The ReadBufferSize value set is less than or equal to zero.
The ReadBufferSize property was set while the stream was open.
The ReadBufferSize property was set to an odd integer value.
Remarks
The ReadBufferSize property ignores any value smaller than 4096.
Because the ReadBufferSize property represents only the Windows-created buffer, it can return a smaller value than the BytesToRead property, which represents both the SerialPort buffer and the Windows-created buffer.
