标题: 利用串口实现短信发送功能的一个国外程序

国外写的一个利用串口连接设备程序，实现设备连接配置-发送短信-读取短信-删除短信功能。大家可以参考下：这个程序只适合发送英文短信，需要发送中文短信需要添加短信收发设备二次开发将uniCode转化为中文的程序才能实现。

public SerialPort OpenPort(string p_strPortName,

int p_uBaudRate, int p_uDataBits,

int p_uReadTimeout, int p_uWriteTimeout)

{

receiveNow = new AutoResetEvent(false);

SerialPort port = new SerialPort();

try

{

      port.PortName =p_strPortName;    //COM1
      port.BaudRate = p_uBaudRate;       //9600
      port.DataBits = p_uDataBits;          //8
      port.StopBits =StopBits.One;          //1
      port.Parity = Parity.None;                //None
      port.ReadTimeout =p_uReadTimeout;          //300
      port.WriteTimeout = p_uWriteTimeout;          //300
      port.Encoding =Encoding.GetEncoding("iso-8859-1");

port.DataReceived += newSerialDataReceivedEventHandler

(port_DataReceived);

port.Open();

port.DtrEnable = true;

port.RtsEnable = true;

}

catch (Exception ex)

{

throw ex;

}

return port;

}

Send SMS

In the second tab, you can send SMS:

public bool sendMsg(SerialPort port, string PhoneNo, string Message)

{

bool isSend = false;

try

{

string recievedData =ExecCommand(port,"AT", 300, "No phone connected");

recievedData =ExecCommand(port,"AT+CMGF=1", 300,

"Failed to setmessage format.");

String command = "AT+CMGS="" + PhoneNo + """;

recievedData =ExecCommand(port,command, 300,

"Failed toaccept phoneNo");

command = Message + char.ConvertFromUtf32(26) + " ";

recievedData =ExecCommand(port,command, 3000,

"Failed to sendmessage"); //3 seconds if(recievedData.EndsWith(" OK "))

{

isSend = true;

}

else if (recievedData.Contains("ERROR"))

{

isSend = false;

}

return isSend;

}

catch (Exception ex)

{

throw new Exception(ex.Message);

}

Read SMS

In the third tab, you can read SMS:

public ShortMessageCollection ReadSMS(SerialPort port)

{

// Set up the phoneand read the messages ShortMessageCollection messages =null;

try

{

#region Execute Command

// Check connection
ExecCommand(port,"AT", 300, "No phone connected");

// Use message format"Text mode"
ExecCommand(port,"AT+CMGF=1", 300, "Failed to setmessage format.");

// Use character set"PCCP437"
ExecCommand(port,"AT+CSCS="PCCP437"", 300,

"Failed to setcharacter set.");

// Select SIM storage
ExecCommand(port,"AT+CPMS="SM"", 300,

"Failed toselect message storage.");

// Read the messages
string input = ExecCommand(port,"AT+CMGL="ALL"", 5000,

"Failed to readthe messages.");

#endregion

#region Parse messages

messages =ParseMessages(input);

#endregion

}

catch (Exception ex)

{

throw new Exception(ex.Message);

}

if (messages != null)

return messages;

else

return null;

}

Delete SMS

In the fourth and last tab, you can count the number of SMS and delete SMSas well.

public bool DeleteMsg(SerialPort port , string p_strCommand)

{

bool isDeleted = false;

try

{

#region Execute Command

string recievedData =ExecCommand(port,"AT", 300, "No phone connected");

recievedData =ExecCommand(port,"AT+CMGF=1", 300,

"Failed to setmessage format.");

String command = p_strCommand;

recievedData =ExecCommand(port,command, 300, "Failed todelete message");

#endregion

if (recievedData.EndsWith(" OK "))

{

isDeleted = true;

}

if (recievedData.Contains("ERROR"))

{

isDeleted = false;

}

return isDeleted;

}

catch (Exception ex)

{

throw new Exception(ex.Message);

}
