I have develpoed a c# application for sending sms using GSMCOMM library of C# .But the problem which i am facing for three days is that when i tried to send the message using the gsmcomm objects.send message methode .Sometimes it gives exception that phone is not connected and sometimes it gives exception port not open.

        string conectionStr = ConfigurationSettings.AppSettings["ConnectionString"].ToString();
        clsFileLogger.VerifyLogFileDirectory();
        clsFileLogger.WriteToLog("DB Connection: " + conectionStr);
        conn = new SqlConnection(@conectionStr);
        int port = Convert.ToInt32(ConfigurationSettings.AppSettings["port"]);
        int baudRate = Convert.ToInt32(ConfigurationSettings.AppSettings["baudRate"]);
        int timeout = Convert.ToInt32(ConfigurationSettings.AppSettings["timeout"]);
        gsmComm = new GsmCommMain(port, baudRate, timeout);
        try
        {
            Isconnected = false;
            if (gsmComm.IsConnected() == false)
            {
                gsmComm.Open();
            }

            Isconnected = gsmComm.IsConnected();

            clsFileLogger.WriteToLog("\nConnected with GSM Modam");
        }
        catch (Exception)
        {
            clsFileLogger.WriteToLog("\nUnable to open the port.");
        }
        return Isconnected;
    }

以及发送短信的代码

And code for sending SMS

  if (gsmComm.IsConnected() == false)
                    {
                        this.ConnectPhone();
                    }

                    pdu = new SmsSubmitPdu(strSMS, cellNO, "");
                    gsmComm.SendMessage(pdu);

 catch (Exception ex)
                {

                    throw ex;
                }

但是似乎您的COM端口打开问题不在您的代码中.尝试使用Teraterm应用之类的工具测试您的端口.并且请确保在您开始运行应用程序时端口未打开(在先前启动后端口可能仍处于打开状态).

But it seems that your problem with com-port opening isn't in your code. Try to test your port using something like Teraterm app. And be sure the port isn't open when you start to run your app (it may be still open after previous launching).
