基于WTK做了个测试程序，部分测试代码如下：
public void mynewsocket(){
StringBuffer buf =new StringBuffer();
try {
String url="socket://211.148.×.×:6666";
byte mybytes[];
mybytes = url.getBytes();
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("1");
MIDlet1.instance.displayable2.mypaint();
buf.append("1");
SocketConnection sc;
sc=(SocketConnection)Connector.open("socket://211.148.×.×:9188");
//sc=(SocketConnection)Connector.open("socket://211.148.×.×:6666");
sc.setSocketOption(SocketConnection.DELAY,1);
sc.setSocketOption(SocketConnection.LINGER,25);
sc.setSocketOption(SocketConnection.KEEPALIVE,1);
sc.setSocketOption(SocketConnection.RCVBUF,1024);
sc.setSocketOption(SocketConnection.SNDBUF,1024);
int myport=sc.getLocalPort();
//String myadd=sc.getLocalAddress();
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append((char)myport);
MIDlet1.instance.displayable2.mypaint();
buf.append("p"+myport);
sc.setSocketOption(SocketConnection.KEEPALIVE,1);
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("2");
MIDlet1.instance.displayable2.mypaint();
buf.append("2");
//sc.setSocketOption();
DataInputStream is = sc.openDataInputStream();
DataOutputStream os= sc.openDataOutputStream();
// DataOutputStreamdo
s = new DataOutputStream(sc.openDataOutputStream());
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("3");
MIDlet1.instance.displayable2.mypaint();
buf.append("3");
//os.writeUTF("hello/n");
os.write(mybytes,0,mybytes.length);
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("4");
MIDlet1.instance.displayable2.mypaint();
buf.append("4");
os.flush();
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("5");
MIDlet1.instance.displayable2.mypaint();
buf.append("5");
//DataInputStream dis= new DataInputStream(sc.openDataInputStream());
String content="";
int ic;
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("6");
MIDlet1.instance.displayable2.mypaint();
buf.append("6");
//buf.append(content);
while((ic=is.read())!= -1)
{
buf.append((char)ic);
}
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("7");
MIDlet1.instance.displayable2.mypaint();
buf.append("7");
is.close();
os.close();
sc.close();
MIDlet1.instance.displayable2.buf1.setLength(0);
MIDlet1.instance.displayable2.buf1.append("8");
MIDlet1.instance.displayable2.mypaint();
buf.append("8");

}
catch (Exception e) {
e.printStackTrace();
}
Form f =new Form("http test");
f.append(buf.toString());
Display.getDisplay(this).setCurrent(f);

}
在计算机的模拟器上运行都正常，收发数据也没问题。但是在手机上实际运行后，只执行到sc=(SocketConnection)Connector.open("socket://211.148.×.×:9188");就抛出了异常。在PC上的服务器软件检测到已经建立了TCP连接
10.21.9.193:32772连接！
10.21.9.193:32772错误！
10.21.9.193:32772断开！
但是一建立连接就立刻报错并断开了Asynchronous socket error 100053；
用手机自带浏览器建立连接，PC软件接收如下信息：

并且收发数据都正常，PC上检测到的连接IP为：211.136.16.41:20517连接！
不是10.0.几的IP。请问为什么？
