Hi Daniele, The network connection is indeed established (I thought this might be the problem)! I guess that the serial forwarder protocol is a binary protocol and that it does not send Strings or carriage returns, so your code will not be able to read lines (though it could read bytes).
The best way to interact with the serial forwarder is probably to use the TinyOS Java libraries. You would have to include the packages that I recommended to you in a previous mail (also on the TinyOS help mailing list): comm, message, packet, and utils (maybe sf and/or tools are needed as well, but I don't think so). In your applet, you could establish the connection to the serial forwarder with code like this: // ------------------------------ String comm = "s...@localhost:9002"; PhoenixSource ps = BuildSource.makePhoenix(comm, PrintStreamMessenger.err); MoteIF mif = new MoteIF(ps); // ------------------------------ of course you'll have to import the appropriate packages and you need to include the TinyOS Java library classes into the jar file of your applet. If you get an error about not being able to load the native libraries, you'll have to modify the appropriate TinyOS library files and remove the corresponding "System.load(..)" lines, they are not really needed for this purpose.
