[C#] Come ottenere una specifica sequenza di output in una comunicazione seriale

**donSalvatore** · 25-03-2009, 12:09

Ciao a tutti.
Ho scritto un programma in C# che implementa una comunicazione con la porta seriale (RS232), ma ho deciso di non utilizzare la classe SerialPort messa a disposizione dal framework.
Il motivo di questa scelta risiede nella necessità di riprodurre una specifica sequenza ottenuta da un monitor di porte seriali (per i miei scopi ho usato questo monitor freeware):

Output da replicare:

codice:

Come si può notare, le differenze sono dalla linea 30 fino alla fine dei log.

Ecco la prima parte di codice (quella restante è inserita nel post successivo a causa del limite sulla lunghezza del messaggio):

Main.cs

codice:

#region Using

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

#endregion

namespace TestAppConsole
{
    class Program
    {
        static void Main()
        {
        	SerialPort serialPort = new SerialPort();
            serialPort.Connect();
        	OverlappedFunction[] functionToOverlap = 
                {
                    OverlappedFunction.SetBaudRate,
                    OverlappedFunction.SetLineControl, 
                    OverlappedFunction.SetRts
                };
            uint setCommMask = 0x000D;
            byte byteToSend = 0xFF;
            serialPort.OverlapCommMask(functionToOverlap, setCommMask);
            Thread.Sleep(14);
            serialPort.GetModemStatus();
            serialPort.TransmitCharOverlap(byteToSend);
            serialPort.Disconnect();
        }
    }
}

OverlappedFunction.cs

codice:

#region Using 

using System;
using System.Collections.Generic;
using System.Text;

#endregion

namespace TestAppConsole
{
    public enum OverlappedFunction
    {
        SetHandFlow = 1,
        SetQueueSize = 2,
        SetTimeOut = 3,
        SetFifoControl = 4,
        ClearRts = 5,
        SetDtr = 6,
        SetBaudRate = 7,
        SetLineControl = 8,
        SetRts = 9,
        GetModemStatus = 10,
    }
}

Qualcuno sa come ottenere l'output da replicare?
Grazie in anticipo
