This enumeration can be useful when handling the SerialPort.ErrorReceived event to detect and respond to errors when communicating data through a SerialPort. You examine the type of error by retrieving the SerialErrorReceivedEventArgs.EventType property. The EventType property contains one of the values from the SerialError enumeration.
