[Tinyos-help] Receiving serial messages from the PC

[Michael Schippling]

You will probably not be able to send message_t's using Hyperterm
because they contain non-ASCII content. Specifically the CRC
value needs to be calculated per-message. I don't use T2 so
I can't fully comment, but whatever modules that implement the
moral equivalent of GenericComm accept a reasonably narrow range
of header and trailer data.

If you want to send your own message format then you need to use the
lower level UART implementation to get and put individual bytes.

Or you can look into the demo programs that use Java or C constructs
to format and send valid message_t's.
