AT命令發送短信在Windows 8.1

我一直在研究了超過兩天，試圖讓一個應用程序無法正常工作使用AT命令發送短信，我實現了在網上提供一些教程和項目。不幸的是，他們都沒有工作。AT命令發送短信在Windows 8.1

[https://docs.google.com/document/d/1VfBbMcKZsutP8Cwg2iu7Rqiyccks1J6N2ZEbkbxnCTU/preview]這段代碼給了我執行命令，但不發送消息。

然後我嘗試了另一個項目（我使用的是C＃和Visual Studio 2013），它具有以下文件，執行後狀態更改爲消息已發送，但我沒有收到消息。我使用華爲移動連接 - 3G的應用程序接口 GSM調制解調器

Program.cs的

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace CSharp_SMS 
{ 
static class Program 
{ 
    /// <summary> 
    /// The main entry point for the application. 
    /// </summary> 
    [STAThread] 
    static void Main() 
    { 
     Application.EnableVisualStyles(); 
     Application.SetCompatibleTextRenderingDefault(false); 
     Application.Run(new Form_SMS_Sender()); 
    } 
} 
}

Form1.cs的

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.IO.Ports; 
using System.Linq; 
using System.Text; 
using System.Threading; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace CSharp_SMS 
{ 
public partial class Form_SMS_Sender : Form 
{ 
    private SerialPort _serialPort; 
    public Form_SMS_Sender() 
    { 
     InitializeComponent(); 
    } 

    private void buttonSend_Click(object sender, EventArgs e) 
    { 
     string number = textBoxNumber.Text; 
     string message = textBoxMessage.Text; 

     _serialPort = new SerialPort("COM17", 19200); //Replace "COM7" with corresponding port name 

     Thread.Sleep(1000); 

     _serialPort.Open(); 

     Thread.Sleep(1000); 

     _serialPort.Write("AT+CMGF=1\r"); 

     Thread.Sleep(1000); 

     _serialPort.Write("AT+CMGS=\"" + number + "\"\r\n"); 

     Thread.Sleep(1000); 

     _serialPort.Write(message + "\x1A"); 

     Thread.Sleep(1000); 

     labelStatus.Text = "Status: Message sent"; 

     _serialPort.Close(); 
    } 
} 
}

有問題的程序？我錯過了什麼？或者，在Windows 8.1中運行這個問題有問題，因爲我還發現有一個名爲MS HyperTerminal的程序，這部分對我來說不是很清楚。

即_tutorial_應刪除（相關帖子：[1]（http://stackoverflow.com/q/28315943/1207195）和[2]（http://stackoverflow.com/a/15591673/ 1207195））。什麼不工作？有什麼異常？根本沒有結果？你必須改變一些串口屬性，不要等待使用Thred.Sleep（），**檢查調制解調器響應**（順便說一下，第一次睡眠是無用的）。我還建議將該代碼移到背景工作者（或者您將掛起UI）。狀態變爲「發送消息」，因爲這是你寫的，調制解調器實際告訴你的是未知的（因爲你沒有閱讀它的答案）。 –

您沒有進行身份驗證。你確定你的SIM卡沒有PIN嗎？超級終端直接發送AT命令（不管你輸入被立即發送。） –

運行此的東西，如SysIntertnals Portmon運行，所以你可以看到從設備是您目前完全忽視了響應（看發出ATV1/AT + CMEE命令以啓用更詳細的響應） –

我在下面的格式使用AT Commands和它的作品。

public bool sendMsg(string smsid, string PhoneNo, string Message, string from, string to) 
{ 
    string recievedData; 
    bool isSend = false; 
    string text = "Hello " + to + ",\n" + Message + "\n\n" + from; 
    if (!port.IsOpen)     
     port = OpenPort(); 
    recievedData = ExecCommand(port, "AT+CMGF=1", 400, "Failed to set message format."); 

    try 
    { 
     //string recievedData; // = ExecCommand(port, "AT", 3000, "No phone connected"); 
     String command = "AT+CMGS=\"" + PhoneNo + "\""; 
     recievedData = ExecCommand(port, command, 1000, "Failed to accept phoneNo"); 
     command = text + char.ConvertFromUtf32(26) + "\r"; 
     recievedData = ExecCommand(port, command, 1000, "Failed to send message"); 
     if (recievedData.Contains("OK")) 
     { 
      isSend = true;     
     } 
     else if (recievedData.Contains("ERROR")) 
     { 
      isSend = false;     
     } 
    } 
    catch (Exception ex) 
    { 
     MyLog.Write(new LogPacket(ex, DateTime.Now)); 
    } 
    return isSend; 
}

我用SMSPDUlib

和代碼

private const string LT = "\r\n"; 

    public void Auth(string pin)

    }

使用Auth()初始化調制解調器和SendSms2()發送短信。

你可以給參數的彙總方式通'flashMsg'和'encoding'此功能'公共字符串SendSms2（字符串phoneNumber，字符串消息，布爾flashMsg，SMS.SMSEncoding編碼）' –

FlashSMS： https://en.wikipedia.org/wiki/Short_Message_Service#Flash_SMS 通常它應該是錯誤的。編碼：用於發送短信的編碼。它可以是_7bit，_8bit或UCS2（類似於Unicode） –

請不要使用'Thread.Sleep'來等待來自調制解調器的''n \ r>「'響應。有關詳細信息，請參閱[此答案]的第一部分（http://stackoverflow.com/a/15591673/23118）。 – hlovdal
