Assembly:  System (in System.dll)

public enum SerialError

Member nameDescription

The hardware detected a framing error.


A character-buffer overrun has occurred. The next character is lost.


An input buffer overflow has occurred. There is either no room in the input buffer, or a character was received after the end-of-file (EOF) character.


The hardware detected a parity error.


The application tried to transmit a character, but the output buffer was full.

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