Yes, of course I'll put the code, however it's quite basic:

Activity script:

var synSocket;
var asynSocket;

asynSocket = new TCPSocket(false);

asynSocket.onConnect = function()
{
System.print("connected");
}

asynSocket.onClose = function()
{
System.print("disconnected")
}

asynSocket.onIOError = function(e)
{
System.print("Error "+e);
}

if (asynSocket.connected == false)
{
//putting 'xml.weather.com' instead of the IP will block the syn socket connection in the page script, if there is no internet access
asynSocket.connect('65.207.183.129', 80, 3000);
}

Page Script:

synSocket = new TCPSocket(true);
synSocket.connect('192.168.0.100', 12000, 500);
socket.write(String.fromCharCode(0xF0, 0xF1, 0xF2));
var data = socket.read(1000,500);
synSocket.close();

Thanks again Lyndel, you really saved me a lot of time !
