L’exemple suivant montre comment définir la StopBits propriété sur One.

SerialPort^ mySerialPort = gcnew SerialPort("COM1");

mySerialPort->BaudRate = 9600;
mySerialPort->Parity = Parity::None;
mySerialPort->StopBits = StopBits::One;
mySerialPort->DataBits = 8;
mySerialPort->Handshake = Handshake::None;
mySerialPort->RtsEnable = true;

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

L’exemple suivant illustre l’utilisation de la SerialPort classe pour permettre à deux utilisateurs de discuter à partir de deux ordinateurs distincts connectés par un câble de modem null. Dans cet exemple, les utilisateurs sont invités à entrer les paramètres de port et un nom d’utilisateur avant de discuter. Cet exemple de code fait partie d’un exemple plus grand fourni pour la SerialPort classe .
