How to Send Multiple writeUTF to Socket in TCP?

Question

So with TCP in AS3, I'm trying to write strings over to the server and then to the clients, but it appears to only be able to read one at a time. This is not good because I'm sending messages based on keys being pressed, and the client has an action that needs to be taken place based on what key is pressed. Since multiple keys can be pressed at a time, obviously it does not work correctly.
Client example:
if (keys[p1_jump_key])
            p1_up = "down";
            sock.writeUTF("p1_up_down");
            sock.flush();
        else
            p1_up = "up";
            sock.writeUTF("p1_up_up");
            sock.flush();
        if (keys[p1_crouch_key])
            p1_down = "down";
            sock.writeUTF("p1_down_down");
            sock.flush();
        else
            p1_down = "up";
            sock.writeUTF("p1_down_up");
            sock.flush();
And then here is the server:
function socketDataHandler(event:ProgressEvent):void{
var socket:Socket = event.target as Socket;
var message:String = socket.readUTF();
for each (var socket:Socket in clientSockets)
        socket.writeUTF(message);
        socket.flush();
And finally, here is the recieving client (I have a method that allows the server to differentiate between the two):
if(msg=="p1_down_down"){
        p1_down="down";
    if(msg=="p1_down_up"){
        p1_down="up";
    if(msg=="p1_up_down"){
        p1_down="down";
    if(msg=="p1_up_up"){
        p1_down="up";
Now many of you may already see the issue, as when the down key is up, it sends the message "p1_down_up". When the up key is up, it sends the message "p1_up_up". Both messages are sending at once when neither of them are being pressed. The receiving client is, I suppose, just getting one of the signals, or perhaps neither of them. How do I make MULTIPLE signals get wrote and read over the server? I tried using an array but you can't write those apparently. Someone please help, I've been reading allover the web for a week with absolutely no answer. Thank you.
