Puerto serie RS232

[Meta]

Hola:

Estoy con MonoDevelop con el openSUSE 11.1. Mirando esta web http://www.mono-project.com/HowToSystemIOPorts quiero configurar el puerto serie como a mi me de la gana.

Lo he puesto así:

Código (csharp) [Seleccionar] Expandir

mySerial new SerialPort("/dev/ttyS0", 9600, None, 8, Two);

La otra manera con comillas así:

Código (csharp) [Seleccionar] Expandir

mySerial new SerialPort("/dev/ttyS0", 9600, "None", 8, "Two");

Código completo:

Código (csharp) [Seleccionar] Expandir

// MainWindow.cs created with MonoDevelop
// User: metaconta at 17:46 23/02/2009
//
// To change standard headers go to Edit->Preferences->Coding->Standard Headers
//
using System;
using Gtk;
using System.IO.Ports;

public partial class MainWindow: Gtk.Window
{
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
Build ();
}

protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{
Application.Quit ();
a.RetVal = true;
}

protected virtual void OnButton1Clicked (object sender, System.EventArgs e)
{
mySerial new SerialPort("/dev/ttyS0", 9600, None, 8, Two);
}
}

Me da error en la línea 25. ¿Qué puede ser?

Estoy intentando pasar este código de Visual C# a Mono, puedes ver el código en las páginas 153 y 154 en este manual en PDF.

Saludos.

EDITO:
He logrado abrir el puerto pero no he sido enviar el código al puerto serie.

if(mySerial == null) return;

mySerial.Open();

if(!mySerial.IsOpen)
{
label1.Text = "Error abriendo";
mySerial.Dispose();
return;
}

byte[] buffer = new byte[1];
buffer[0] = 0x74;
mySerial.Write(buffer, 0, 1);

try
{
mySerial.Write(buffer, 0, 1);
}
catch(Exception ex)
{
//label1.Text = ex.Message;// + " " + ex.StackTrace;
mySerial.Close();
mySerial.Dispose();
return;
}

mySerial.Close();
}
}

Un cordial saludo.

Vamos a empezar desde el principio.

Utilizando el Mono con gtk#, he introducido un botón normal en el formulario. El código completo lo he hecho de nuevo y ahora es así. Ejecuta sin problemas pero al pulsar el botón hay errores que no se el motivo.

protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{

a.RetVal = true;
}

public SerialPort mySerial;

protected virtual void OnButtonTClicked (object sender, System.EventArgs e)
{
mySerial = new SerialPort("/dev/ttyS0", 9600, Parity.None, 8, StopBits.Two);
mySerial.Open();
byte[] mBuffer = new byte[1];
mBuffer[0] = 0x74; // LA letra t.
mySerial.Write(mBuffer, 0, mBuffer.Length);
mySerial.Close();
}
}
