Identify

From ScapeFX Wiki

The telnet negotiator used in ScapeFX will identify the client through the TELOPT_TTYPE as:

SERVER: IAC DO TELOPT_TTYPE
CLIENT: IAC WILL TELOPT_TTYPE
SERVER: IAC SB TELOPT_TTYPE SEND IAC SE
CLIENT: IAC SB TELOPT_TTYPE IS ScapeFX IAC SE

If you do not wish to use the telnet protocol to identify the client you can write your own plugins for it. You can for example use the ScapeFXPlugin_NetworkConnect to immediately send something from the client when it has made a connection to the game server.

Example:

public class MyConnect extends ScapeFXPlugin_NetworkConnect{
    @Override
    public void performAfterConnect() {
        this.getNetwork().send("Hello!");
    }
    @Override
    public String getPluginInfo() {
        return "Plugin for sending something after connection is established.";
    }
    @Override
    public String getPluginName() {
        return "MyConnect";
    }
}
