谁可以发给我个在windows下能用的JAVA串口通信啊~~要可以用的

Answer 1

下面是Java   串口通信的核心代码,希望对你有用! 
import   java.io.*; 
import   java.util.*; 
import   javax.comm.*; 
public   class   SimpleRead   implements   Runnable,   SerialPortEventListener   { 
        static   CommPortIdentifier   portId;

        SerialPort   serialPort; 
        Thread   readThread; 
        public   static   void   main(String[]   args)   { 
                portList   =   CommPortIdentifier.getPortIdentifiers(); 
                while   (portList.hasMoreElements())   { 
                        portId   =   (CommPortIdentifier)   portList.nextElement(); 
                        if   (portId.getPortType()==CommPortIdentifier.PORT_SERIAL)   { 
                                if   (portId.getName().equals( "COM1 "))   { 
                                        SimpleRead   reader   =   new   SimpleRead(); 
                                } 
                        } 
                } 
        } 
        public   SimpleRead()   { 
                try   {//打开串口COM1 
                        serialPort   =   (SerialPort)   portId.open( "SimpleReadApp ",   2000); 
                }   catch   (PortInUseException   e)   {} 
                try   {//获得输入输出流 
                        inputStream   =   serialPort.getInputStream(); 
　outputStream   =   serialPort.getOutputStream(); 
                }   catch   (IOException   e)   {} 
try   {//为串口添加监听器 
                        serialPort.addEventListener(this); 
}   catch   (TooManyListenersException   e)   {} 
                serialPort.notifyOnDataAvailable(true); 
                try   {//配置串口 
                        serialPort.setSerialPortParams(9600,//波特率9600bps 
                                SerialPort.DATABITS_7,//7位数据位 
                                SerialPort.STOPBITS_1,//1位停止位

                readThread.start();//启动线程 
        } 
        public   void   run()   { 
                try   { 
                        Thread.sleep(20000); 
                }   catch   (InterruptedException   e)   {} 
        } 
        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.DSR: 
                case   SerialPortEvent.RI: 
                case   SerialPortEvent.OUTPUT_BUFFER_EMPTY: 
                        break; 
                case   SerialPortEvent.DATA_AVAILABLE://如果有数据到达 
                        byte[]   readBuffer   =   new   byte[20]; 
                        try   { 
                                while   (inputStream.available()   >   0)   { 
//读取一个字节到readBuffer 
                                        int   numBytes   =   inputStream.read(readBuffer); 
                                } 
                                System.out.print(new   String(readBuffer)); 
                        }   catch   (IOException   e)   {} 
                        break; 
                } 
        } 
} 

Answer 2

comm.jar 可以从我的网站，或者我在CSDN的资源里找到import java.util.Enumeration;import javax.comm.CommPortIdentifier;public class TestCom {
  public static void main(String argv[]) {
    new TestCom();
  }  public TestCom() {
    CommPortIdentifier portId;    Enumeration ports = CommPortIdentifier.getPortIdentifiers();    if (ports == null) {
      System.out.println("No comm ports found!");
      return;
    }    // print out all ports
    System.out.println("printing all ports...");
    while (ports.hasMoreElements()) {
      System.out.println(" " + ((CommPortIdentifier) ports.nextElement()).getName());    }
  }}
