how to get the "line turnaround" prompt with apache telnet

Question

I'm using Apache telnet for connecting to a MUD game.

Here's my output:

thufir@dur:~$ 
thufir@dur:~$ 
thufir@dur:~$ java -jar NetBeansProjects/Teln/dist/Teln.jar

wheras here's the standard telnet output:

Enter your ACCOUNT name (not your character name):

This is, I think, because of how lines are handled in StreamReader:

package teln;

import static java.lang.System.out;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class StreamReader {

    private String prompt = "/[#]/";
    private LineParser lp;
    Connection c;

    public StreamReader(Connection c) throws IOException, InterruptedException  {
        this.c = c;
        lp = new LineParser(c);
        readInputStream();
        c.login();
    }

    private void readInputStream() throws IOException, InterruptedException {
        out.println("reading...");
        InputStream inputStream = c.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
        StringBuilder sb = new StringBuilder();
        BufferedReader br = new BufferedReader(inputStreamReader);
        String line = br.readLine();

        while (line != null) { //never terminates...
            sb.append(line);
            line = br.readLine();
            lp.parseLine(line);
        }
    }

    public void setPrompt(String prompt) {
        this.prompt = prompt;  //need to determine EOL somehow...
    }

}

I'm fairly sure it's while (line != null) { in readInputStream which is problematic. Not every line is getting passed, I think.
