UIRobot控制器和C中的程序＃

Question

我有這個來自UIRobot的控制器。這裏是手冊：enter link description here 我想編寫軟件來控制它在C＃中。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.IO.Ports; 

namespace hhh 
{ 

    class Program 
    { 
     static void Main(string[] args) 
     { 
      string ot = "Port je otvoreny"; 
      string za = "Port je zavrety"; 
      string COM = "COM1"; 
      string command = "ENABLE"; 

      SerialPort sp = new SerialPort(COM, 9600); 
      sp.Open(); 

      if (sp.IsOpen) 
      { 
       Console.WriteLine(ot); 
       sp.Write(command); 
       sp.ReadLine(); 
      } 

      else 
      { 
       sp.Write(za); 
      } 

      Console.ReadKey(); 
     } 
    } 
} 

在手冊中是命令ENABLE來初始化控制器，但它不能在我的代碼中工作。我如何發送命令或我犯了什麼錯誤？

我學到了一些新東西，所以這裏是更新我的代碼和新問題。 我想要接收電機的位置。有命令「POS」它必須給我的價值，但我得到的問號（？）而不是數字值的消息框。爲什麼？

     Application.Exit(); 
    } 

    private void fbk_Click(object sender, EventArgs e) 
    { 
     sp.Write("POS;"); 
     string msg = sp.ReadExisting(); 
     MessageBox.Show(msg); 
    } 

} 
}

根據該文件，命令是「ENABLE;」你必須包括分號。因此，將您的代碼更改爲：

string command = "ENABLE;";
