9600, Parity.None, 8, StopBits.One);

// Instatiate this class
new SerialPortProgram();
}

private SerialPortProgram()
{
//Console.WriteLine("Incoming Data:");

// Attach a method to be called when there
// is data waiting in the port's buffer
port.DataReceived += new
SerialDataReceivedEventHandler(port_DataReceived);

// Begin communications
port.Open();

// Enter an application loop to keep this thread alive
Application.Run();

I taught that ExitThread might exit once the method exits as well, but I haven't tried. Anyway, if ExitThread doesn't solve the problem, then Exit will certainly kill it dead :)

I'm not sure that Zoran's suggestion will work (apologies to him if it does) because the SerialPort_DataReceived eventhandler is called on a secondary thread and you need to call Application.ThreadExit() on the thread on which the message loop is running.

I'd try Application.Exit() instead or, if that doesn't work, Environment.Exit(1).

After port.Close(); add this:
Application.ExitThread();

That will exit the message loop on current thread which was started with Application.Run(), and consequently thread and application should exit.
