Listen uses, I believe, PacketSource.readPacket() to get a message.
There is a parallel PacketSource.writePacket(data) method which
sends an appropriately formatted packet after doing magical
protocol and crc transformations. Formatting the "data"
is tricky, my code does it by brute force. The MIG message
class generator may provide some utility in this respect
but I tend to want to do things myself.
In the T1 tools tree you can find
java/net/tinyos/oscope/OscopeResetMsg.java
which is the class for the Reset message I mentioned.
It is used in
java/net/tinyos/oscope/GraphPanel.java
which sounds like it should do GUI stuff but actually
seems to do the real work of the O'scope program.
