掌上電腦的紅外命令

Question

我有一個紅外遙控器，我想用我的PPC替換它。 我的神達P550有一個紅外串行端口，但我不知道如何檢索和重新發送字節序列..... 這可能獲得與.net的SerialPort組件的數據這傾斜？

感謝

你需要寫兩（2）方法和對您的通信的每一端安裝：一個發送和接收。

的通用發送程序將發出一個消息一些主機監聽特定端口號。下面是一個簡單的例子：

public static void Send(string message, string host, int port) { 
    if (!String.IsNullOrEmpty(message)) { 
    if (port < 80) { 
     port = DEF_PORT; 
    } 
    Byte[] data = Encoding.ASCII.GetBytes(message); 
    using (var client = new TcpClient(host, port)) { 
     var stream = client.GetStream(); 
     stream.Write(data, 0, data.Length); 
     stream.Close(); 
     client.Close(); 
    } 
    } 
} 

的通用接收日常需要知道端口號上偵聽，並應其接收返回數據。下面是它的一個簡單的例子：

public static string Receive(int port) { 
    string data = null; 
    listener = new TcpListener(IPAddress.Any, port); 
    listener.Start(); 
    using (var client = listener.AcceptTcpClient()) { // waits until data is avaiable 
    int MAX = client.ReceiveBufferSize; 
    var stream = client.GetStream(); 
    Byte[] buffer = new Byte[MAX]; 
    int len = stream.Read(buffer, 0, MAX); 
    if (0 < len) { 
     data = Encoding.UTF8.GetString(buffer, 0, len); 
    } 
    stream.Close(); 
    client.Close(); 
    } 
    return data; 
} 

下面是我用這個類的完整代碼：

using System; 
using System.Net; 
using System.Net.Sockets; 
using System.Text; 
using System.Windows.Forms; 

namespace AcpMobile5 { 

    class TestClass1 : Form { 

    public const int DEF_PORT = 8000; 
    private static TcpListener listener; 

    public static string Receive(int port) { 
     string data = null; 
     listener = new TcpListener(IPAddress.Any, port); 
     listener.Start(); 
     using (var client = listener.AcceptTcpClient()) { // waits until data is avaiable 
     int MAX = client.ReceiveBufferSize; 
     var stream = client.GetStream(); 
     Byte[] buffer = new Byte[MAX]; 
     int len = stream.Read(buffer, 0, MAX); 
     if (0 < len) { 
      data = Encoding.UTF8.GetString(buffer, 0, len); 
     } 
     stream.Close(); 
     client.Close(); 
     } 
     return data; 
    } 

    public static void Send(string message, string host, int port) { 
     if (!String.IsNullOrEmpty(message)) { 
     if (port < 80) { 
      port = DEF_PORT; 
     } 
     Byte[] data = Encoding.ASCII.GetBytes(message); 
     using (var client = new TcpClient(host, port)) { 
      var stream = client.GetStream(); 
      stream.Write(data, 0, data.Length); 
      stream.Close(); 
      client.Close(); 
     } 
     } 
    } 

    } 

}
