我正在尝试在 windows-7 上制作一个简单的 java 应用程序，它可以在我的 citycell Zoom USB 调制解调器上发送短信。我使用 AT 命令（http://www.canarysystems.com/nsupport/CDMA_AT_Commands.pdf）。流动我的Java代码：
import javax.comm.*;
import java.io.*;
import java.util.*;
public class SimpleWrite implements Runnable, SerialPortEventListener {
public void run() {
}
static Enumeration portList;
static CommPortIdentifier portId;
static String messageString = "AAA";
static char ch = '"';
static String dest = ch + "01739557775" + ch; // 11 Digit Mobile Number.
static InputStream inputStream;
static SerialPort serialPort;
static OutputStream outputStream;
public void serialEvent(SerialPortEvent event) {
switch (event.getEventType()) {
case SerialPortEvent.BI:
case SerialPortEvent.OE:
case SerialPortEvent.FE:
case SerialPortEvent.PE:
case SerialPortEvent.CD:
case SerialPortEvent.CTS:
case SerialPortEvent.DSR:
case SerialPortEvent.RI:
case SerialPortEvent.OUTPUT_BUFFER_EMPTY:
break;
case SerialPortEvent.DATA_AVAILABLE: {
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line = "";
try {
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
System.err.println("Error while reading Port " + e);
}
break;
}
} //switch
}
public SimpleWrite(SerialPort serial) {
try {
inputStream = serial.getInputStream();
try {
serial.addEventListener(this);
} catch (TooManyListenersException e) {
System.out.println("Exception in Adding Listener" + e);
}
serial.notifyOnDataAvailable(true);
} catch (Exception ex) {
System.out.println("Exception in getting InputStream" + ex);
}
}
public static void main(String[] args) {
String line1 = "AT+CSMS=1\r\n";
String line2 = "AT+CMGS=" + dest + "\r\n";
String line3 = messageString + "\r\n";
portList = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
if (portId.getName().equals("COM13")) {
System.out.println("SMS Sending....Port Found");
try {
serialPort = (SerialPort) portId.open("SimpleWriteApp", 2000);
SimpleWrite wr = new SimpleWrite(serialPort);
} catch (PortInUseException e) {
System.out.println("Port In Use " + e);
}
try {
outputStream = serialPort.getOutputStream();
} catch (IOException e) {
System.out.println("Error writing to output stream " + e);
}
try {
serialPort.setSerialPortParams(9600, SerialPort.DATABITS_8, SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);
} catch (UnsupportedCommOperationException e) {
}
try {
outputStream.write(line1.getBytes());
outputStream.write(line1.getBytes());
outputStream.write(line2.getBytes());
outputStream.write(line3.getBytes());
outputStream.write(26);
outputStream.flush();
} catch (Exception e) {
System.out.println("Error writing message " + e);
}
}
}
}
}
/**
* show text in the text window
*
* @param Text text string to show on the display
*/
public static void showText(String Text) {
System.out.println(Text);
}
}
输出：
SMS Sending....Port Found
AT+CSMS=1
ERROR
AT+CSMS=1
ERROR
AT+CMGS="01739557775"
ERROR
请帮我。
