Query to online game server to get its status Delphi - Indy 10

Question

I am trying to find out how to establish a connection between a Delphi application and an online game server in this case Minecraft running with Bukkit.

The search was not successful, but I have a vague idea using maybe Indy 10 components? like TIdTCPClient but I think it needs a handler, I dont know which one.

Then I want to ask.

How to query an online server?

With PHP: https://github.com/FunnyItsElmo/PHP-Minecraft-Server-Status-Query

Any idea coming up?

Sorry for my English Thanks.

As MJN said, once you Connect() to the server, you use the TIdIOHandler.IOHandler property to read/write data as needed, eg:

var
  data: TIdBytes;

Client.Host := AHost;
Client.Port := APort;
Client.ConnectTimeout := 3000;
Client.ReadTimeout := 3000;

Client.Connect;
try
  Client.IOHandler.Write(Byte($FE));
  Client.IOHandler.Write(Byte($01));
  Client.IOHandler.ReadBytes(data, 2048);
finally
  Client.Disconnect;
end;

// parse data as needed...
