 tells Listen tool to use the serial port /dev/ttyUSB0 at the correct speed for a telosb mote.
 
+Listen creates a packet source and just prints out every packet it sees. Output should look something like this:
+{{{

+We use MsgReader to print out the messages. 
+
+{{{
+
+node1-2:~# java net.tinyos.tools.MsgReader -comm serial@/dev/ttyUSB0:telosb BlinkToRadioMsg
+
+}}}
+
+MsgReader reads the packet send to the serial port, looks at its AM type, and if it matches the AM type of one of the Java message classes passed at the command line, it prints out the packet. We see the output like this:
+
+{{{
