高分求解决:把短信猫收短信做成了windows服务,发送AT指令,没有返回值,怎么回事,求高手解决？

如题//开始

            uint MobPort = uint.Parse(XmlHelper.GetValue("Config.xml", "port"));
            sp.BaudRate = 9600;
            sp.PortName = "COM" + MobPort.ToString();
            //如果串口已经打开 则先关闭
            if (sp.IsOpen)
                sp.Close();
            sp.Open();
            //初始化设备
            if (sp.IsOpen)
            {                sp.Write("ATE0\r");
                Thread.Sleep(50);
                sp.Write("AT+CMGF=0\r");//选择短消息信息格式：0-PDU;1-文本
                Thread.Sleep(50);
                sp.Write("AT+CNMI=2,1\r");//（新sms来时送出脉冲）
                Thread.Sleep(50);
                Log.WriteLog("设备就绪！");
                //Log.WriteLog("准备开启接收短信");
                TCheckNewSms();
                //timer_CheckNewSms.Enabled = true;
                //Log.WriteLog("接收短信成功开启");
            }
        }
        /// <summary>
        /// 开启新进程启动检查是否有新短信
        /// </summary>
        private void TCheckNewSms()
        {
            Thread t = new Thread(new ThreadStart(CheckNewSms));
            t.Start();
        }
        /// <summary>
        ///  检测 是否收到新短信(收取所有短信息)
        /// </summary>
        private void CheckNewSms()
        {
            if (sp.IsOpen)
            {
                StringBuilder sb = new StringBuilder();
                sp.RtsEnable = true;//Added By Tan In 2011-07-28
                sp.Write("AT+CMEE=1\r");
                Thread.Sleep(300);
                sp.Write("AT+CMGL=4\r");
                Log.WriteLog("执行AT指令：AT+CMGL=4！");
                //接收数据 循环读取数据 直至收到“OK”或“ERROR”
                try
                {
                    string temp = string.Empty;
                    while (temp.Trim() != "OK" && temp.Trim() != "ERROR")
                    {
                        temp = sp.ReadLine();
                        Log.WriteLog("Temp：" + temp);
                        sb.Append(temp);
                    }
                    Log.WriteLog(sb.ToString());
                }
                catch (Exception ex)
                {
                    Log.WriteLog(ex.Message);
                    //throw ex;
                }
                Thread.Sleep(300);
                if (sb.ToString() != "")
                {
                    Log.WriteLog(sb.ToString());
                }
            }
        }结果在记录日志的txt文件里，看到如下信息：
2011-7-29 15:26:02==设备就绪！
2011-7-29 15:26:03==执行AT指令：AT+CMGL=4！可以看到temp = sp.ReadLine();这个就没有返回值
怎么回事,有木有大侠知道？

解决方案 »

  1.   

    你这个sp中有Write“OK”或"ERROR"吗？如果没有，你那个循环岂不是死循环。。
      

  2.   

    这个不管有没有
    Log.WriteLog("Temp：" + temp);
    这个总得执行吧
    执行了，那日志文件中就得有   Temp:   吧
    可是现在没有
