Question

我正在尝试制作一个发送短信的程序。我编写了程序，但没有成功发送消息。我的程序向我的计算机中的端口COM发送At命令，但我没有从我的gsm调制解调器得到响应。我正在使用COM终端（Temp pro ...）使用at命令发送短信，我可以发送短信。因此，我不知道为什么程序无法发送短信。

public class prawiefinal {
    static Enumeration portList;
    static CommPortIdentifier portId;
    static String messageString = "AT+CMGF=1 \r";
    static String messageString2 = "AT+CMGS=\"+4866467xxxx\"\r";
    static String messageString3 = "TESting \u001A\r\n";
    static SerialPort serialPort;
    static OutputStream outputStream;


    public static void main(String[] args) throws InterruptedException {
        portList = CommPortIdentifier.getPortIdentifiers();

        while (portList.hasMoreElements()) {

            portId = (CommPortIdentifier) portList.nextElement();
            if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {

                if (portId.getName().equals("COM3")) {

                    try {
                        serialPort = (SerialPort)
                            portId.open("COM3", 2000);
                    } catch (PortInUseException e) {System.out.println("err");}
                    try {
                        outputStream = serialPort.getOutputStream();
                    } catch (IOException e) {e.printStackTrace();}

                        Thread.sleep(3000); 
                        outputStream.flush();

                        outputStream.write(messageString2.getBytes());  
                        Thread.sleep(3000);  
                        outputStream.flush();

                        outputStream.flush();
                        System.out.println(messageString);  
                        Thread.sleep(3000);






                        outputStream.close();
                        serialPort.close();

                    } catch (IOException e) {e.printStackTrace());}
                }
            }
        }
    }
}

好的我制作了该程序，我可以发送短信。我使用CTRL + Z和Enter这是一个问题。：D

import java.io.*; 
import java.util.*; 
import gnu.io.*; 

public class SMSsender { 
static Enumeration portList; 
static CommPortIdentifier portId; 
static String messageString1 = "AT";
static String messageString2 = "AT+CPIN=\"7078\"";
static String messageString3 = "AT+CMGF=1"; 
static String messageString4 = "AT+CMGS=\"+4866467xxxx\"";


static String messageString5 = "TESTY2";
static SerialPort serialPort;
static OutputStream outputStream;
static InputStream inputStream;
static char enter = 13;

static char CTRLZ = 26;
public static void main(String[] args) throws InterruptedException {
 portList = CommPortIdentifier.getPortIdentifiers();



while (portList.hasMoreElements()) {

    portId = (CommPortIdentifier) portList.nextElement();
    if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {

         if (portId.getName().equals("COM3")) {

            try {
                serialPort = (SerialPort)
                    portId.open("COM3", 2000);
            } catch (PortInUseException e) {System.out.println("err");}
            try {
                outputStream = serialPort.getOutputStream();
                inputStream = serialPort.getInputStream();
            } catch (IOException e) {e.printStackTrace();}
            try {
                serialPort.setSerialPortParams(9600,
                    SerialPort.DATABITS_8,
                    SerialPort.STOPBITS_1,
                    SerialPort.PARITY_NONE); 
            } catch (UnsupportedCommOperationException e) {e.printStackTrace();}
            try { 

                outputStream.write((messageString1 + enter).getBytes());


                Thread.sleep(100); 
                outputStream.flush();

                outputStream.write((messageString2 + enter).getBytes()); 

                 Thread.sleep(100); 
                 outputStream.flush();

                outputStream.write((messageString3 + enter).getBytes());

                Thread.sleep(100); 
                outputStream.flush(); 




                outputStream.write((messageString4 + enter).getBytes()); 

                Thread.sleep(100);  
                outputStream.flush();

               outputStream.write((messageString5 + CTRLZ).getBytes());  

                outputStream.flush(); 
                Thread.sleep(100); 


    System.out.println("Wyslano wiadomosc");  
    Thread.sleep(3000);


    outputStream.close();
    serialPort.close();
    System.out.println("Port COM zamkniety"); 

            } catch (IOException e) {e.printStackTrace();}
        }
    }
}

} }

使用Java将命令发送到gsm调制解调器
