[Tinyos-help] SerialForwarder invisible to the user.

[Javier .]

Hi, I'm trying to use SerialForwarder in my aplication, but Iwant to do it 
invisible to the user.
Is not dificult to start listening to the serial port with the "-no-gui" 
option. The problem begins when I stop SerialForwarder listening to the 
port. If I try to start listening again, this advise apears:

[EMAIL PROTECTED]:57600 died - restarting (java.io.IOException: Port COM3 busy)
SF enabled, 1 client, 0 packets read, 0 packets written SF enabled, 1 
client, 0 packets read, 0 packets written SF enabled, 1 client, 0 packets 
read, 0 packets written

SF disabled, 1 client, 0 packets read, 0 packets written

Followed by this error message:

java.io.IOException: Port COM3 busy
        at 
net.tinyos.packet.SerialByteSource.openStreams(SerialByteSource.java:69)
        at net.tinyos.packet.StreamByteSource.open(StreamByteSource.java:51)
        at net.tinyos.packet.Packetizer.openSource(Packetizer.java:119).........

This is my code:

        public synchronized void startDetecting(){
                if (sf==null){
                        try {
				sf = new SerialForwarder(new String[] 
{"-quiet","-no-gui","-comm","[EMAIL PROTECTED]"+serialPort+":mica2","-port","9001"});
                        } catch (IOException e) {
                                e.printStackTrace();
                        }
                }
                else{
                        sf.startListenServer();
                }
                waitingForConnection = new Vector(0);
                moteif = new MoteIF(PrintStreamMessenger.err);
                moteif.registerListener(new ConnectionMsg(),this);
                detecting=true;
        }

        public synchronized void stopDetecting(){
                moteif.deregisterListener(new ConnectionMsg(),this);
                sf.listenServerStopped
                sf.stopListenServer();
                detecting=false;
        }

I'm using the 1.1.15 CVS version.
The only thing I want is to have a variable called sf of the type 
SerialForwarder in order to start and stop listening when the user wants but 
without the SerialForwarder gui.

Thanks in advance.
