初学，都不知道该在哪里提问。用JAVA做串口编程改怎么做？

Question

或者相关资料也可以，http://www.gjwtech.com/serialcomm.htm 这个网站的就不用给我了。

Answer 1

先从sun下载javax.comm包
以下是一个发送at命令到com口的程序:
import java.io.*;
import java.util.Enumeration;
import javax.comm.*;public class SimpleWrite
{    static Enumeration portList;
    static CommPortIdentifier portId;
    static SerialPort serialPort;
    static OutputStream outputStream;
    static InputStream inputStream;
    static char c34;
    static char c26 = '\032';
    static String mString1 = "AT+CSCA=[phone]" + "\n";
    static String mString2="AT+CMGF=1" + "\n";
    static String mString3="AT+CMGS=\"+86136.....\"" + "hello" + '\032'+"\n";
//static String messageString1 = "AT+CMGS=\"136.....\"\n\r";
//static String messageString2 = "Got this Message? \u001A\r";
    public SimpleWrite()
    {
    }    public static void main(String args[])
        throws Exception
    {

CommPortIdentifier commportidentifier = CommPortIdentifier.getPortIdentifier("COM2");
        serialPort = (SerialPort)commportidentifier.open("sms app", 3000);
        try
        {
            outputStream = serialPort.getOutputStream();
            inputStream = serialPort.getInputStream();
        }
        catch(IOException ioexception)
        {
        }
        try
        {
           serialPort.setSerialPortParams(9600,
           SerialPort.DATABITS_8,
           SerialPort.STOPBITS_1,
           SerialPort.PARITY_NONE);        }
        catch(UnsupportedCommOperationException unsupportedcommoperationexception)
        {
           
        }        try
        {
            outputStream.write(mString1.getBytes());
            outputStream.write(mString2.getBytes());
            outputStream.write(mString3.getBytes());
   outputStream.flush();
   outputStream.close();        }
        catch(IOException ioexception1)
        {
        }
    }}
