NetStream : send text data

Question

hi,
I try to do a really simple chat with NetStream. I would like to send a text on my netstream (I don't want to use camera, only text !)
I run a red5 server and I use flex 4.5
As I my new, I don't understand what is the best way to do this. I try code to send video streaming and it works but I can't send text.
Is somebody have a really simple example to do this ?

//Simple solution,
import flash.events.*
public var chat_so:SharedObject;
public var nc:NetConnection;
public var username:String;
public function createConnection():void
    nc = new NetConnection();
    nc.objectEncoding = ObjectEncoding.AMF0;
    nc.addEventListener( NetStatusEvent.NET_STATUS, netStatusHandler );
    nc.connect( "rtmp://path_to_red5/oflaDemo",username);
//Then in the netStatusHandler you would need something like this....
public function netStatusHandler( event:NetStatusEvent ):void
    switch( event.info.code )
        case "NetConnection.Connect.Success":
             connectComponents()
        break;
        case "NetConnection.Connect.Rejected":
        break;                   
//This sets up a SyncEvent handler...
public function connectComponents():void
    SharedObject.defaultObjectEncoding  = flash.net.ObjectEncoding.AMF0;
    chat_so = SharedObject.getRemote("chat_so", nc.uri, false);
    chat_so.addEventListener( SyncEvent.SYNC, usersSyncHandler_chat );
    chat_so.connect( nc );
//This fires when the sharedObject is updated...
public function usersSyncHandler_chat( event:SyncEvent ):void
        var results:Object = event.target.data;
        for( var a:String in results )
        if (  results[ a ] != undefined )
             //this will add a message to a text component...
            chatCanvas.htmlText += "" + results[ a ];
            chatCanvas.validateNow();
            chatCanvas.verticalScrollPosition = chatCanvas.maxVerticalScrollPosition;
//this button or key listener function will send a message by updating a sharedObject on all clients...
public function sendMessage():void
      //grab message from an input text component.
      var msg:String = chatInputTxt.text;
      //send the msg...
      chat_so.setProperty("textValue", username + ": " + msg );
      //clear text from chatInputTxt.text
      chatInputTxt.text = "";
