Examples

The following example shows how to set the StopBits property to One.

SerialPort mySerialPort = new SerialPort("COM1");

mySerialPort.BaudRate = 9600;
mySerialPort.Parity = Parity.None;
mySerialPort.StopBits = StopBits.One;
mySerialPort.DataBits = 8;
mySerialPort.Handshake = Handshake.None;
mySerialPort.RtsEnable = true;

Dim mySerialPort As New SerialPort("COM1")

mySerialPort.BaudRate = 9600
mySerialPort.Parity = Parity.None
mySerialPort.StopBits = StopBits.One
mySerialPort.DataBits = 8
mySerialPort.Handshake = Handshake.None
mySerialPort.RtsEnable = True

The following code example displays the possible values of the StopBits enumeration to the console, then prompts the user to choose one. This code example is part of a larger code example provided for the SerialPort class.

public static StopBits SetPortStopBits(StopBits defaultPortStopBits)
{
    string stopBits;

    Console.WriteLine("Available StopBits options:");
    foreach (string s in Enum.GetNames(typeof(StopBits)))
    {
        Console.WriteLine("   {0}", s);
    }

    Console.Write("Enter StopBits value (None is not supported and \n" +
     "raises an ArgumentOutOfRangeException. \n (Default: {0}):", defaultPortStopBits.ToString());
    stopBits = Console.ReadLine();

    if (stopBits == "" )
    {
        stopBits = defaultPortStopBits.ToString();
    }

    return (StopBits)Enum.Parse(typeof(StopBits), stopBits, true);
}

' Display StopBits values and prompt user to enter a value.

Public Shared Function SetPortStopBits(defaultPortStopBits As StopBits) As StopBits
    Dim stopBits As String

    Console.WriteLine("Available StopBits options:")
    For Each s As String In [Enum].GetNames(GetType(StopBits))
        Console.WriteLine("   {0}", s)
    Next

    Console.Write("Enter StopBits value (None is not supported and " &
                  vbLf & "raises an ArgumentOutOfRangeException. " &
                  vbLf & " (Default: {0}):", defaultPortStopBits.ToString())
    stopBits = Console.ReadLine()

    If stopBits = "" Then
        stopBits = defaultPortStopBits.ToString()
    End If

    Return CType([Enum].Parse(GetType(StopBits), stopBits, True), StopBits)
End Function

Remarks

You use this enumeration when setting the value of the StopBits property on the SerialPort class. Stop bits separate each unit of data on an asynchronous serial connection. They are also sent continuously when no data is available for transmission.

The SerialPort class throws an ArgumentOutOfRangeException exception when you set the StopBits property to None.
