IIRC, there's a simple handshake in the beginning of the communication.
Are the two bytes something like uppercase T and some other value? I
think you must reply with the same bytes to begin communicating.

Subject: Re: [Tinyos-help] How to read data from SerialForwarder
Since I know Jack (forgive the technical language) about C#, I'll just
hazard a guess that trying to convert the binary message to an ASCII
string is probably a bad idea, since there is no text in the message.
How many bytes does it say it received? Should be around 34 or so. If
that's what you get then try a byte by byte conversion to numeric
strings to display in your text window.
