socket callback

hi there.

i want my scrip to react on messages from a socket.

i tried something like this.

Test.prototype.constructor = Test;
function Test()
{
    this.socket = new Socket;
    this.socket.timeout = 10;
    var con = this.socket.open("127.0.0.1:9876","UTF-8");
}
Test.prototype.test = function()
{
    var target = 'indesign-8.0';
    var m = new BridgeTalk();
    m.target = 'indesign-8.0';
   
    
        while(true)
    {
        
        var res = this.socket.read();
        if(res.length > 0)
        {
         m.send();
            alert(res);
            }
            else
            $.sleep(50);
    }
    Model.init();
}
var t = new Test();
t.test();

this kind of works. an "alert" is shwon every time i send a message from the other side.

but the while loop will block everything else. is there a way to prevent this?

i also had the idea to implement a threaded socket in a c++ library, but it seems i can non use callbacks from an external object?

i can not see a way of calling a javascript function from my c++ library. i can only react on calls.

please ask if i'm not clear as to what i'm trying to do.

cheers
