How to Make Multiplayer TCP Flash Game?

I have a game in the works, and though I got the UDP to work perfectly, I sadly later found out that that is simply just a lossy protocol. There's apparently (as far as my knowledge goes) nothing you can do to make it resend data if the data was not received successfully by the recipient.

So, I was wondering how to use TCP? I've heard it's possible, but I can't seem to find a single tutorial or any information anywhere on how to do it. I found on Adobe's site socket connections, and though I got the server to connect (I think), I have no clue how to send data to it, how to get other clients to connect to it, etc. Any help?

This is the script I've been using, and though it does connect... that's basically all it does, I don't know where to go from here...
