Dear all,
  Now I am going through Lesson 7 of the tutorial, and an error occured when 
the code going.
   
  Mine sensor is a telosb node, I installed the apps/TOSBase code into it, 
  and then start SerialForwarder with command:
  java net.tinyos.sf.SerialForwarder -comm [EMAIL PROTECTED]
  then start BcastInject with command:
  export [EMAIL PROTECTED]:19200
  java net.tinyos.tools.BcastInject  led_on
  but the program failed, with an error:
  [EMAIL PROTECTED]:19200 died - exiting (java.io.IOException: Port COM9 busy)
   
  I have spent a lot time to find how to fix this problem, but failed,I am even 
puzzled Do I need to start Serial Forwarder when running BcastInject?
  could anyone help me or give me some advice??
  really thanks 
  Sam
