Trouble with custom InputStream being used by Readers

For some reason the following InputStream gives subclasses of Reader a
hard time because they seem to be unable to read the data. What is
wrong with my Stream. Ex. With the BufferedReader class when I call
the readLine() method it blocks forever even though there are a couple
of \n in the data that is being outputted. Also I know my stream
works because the read() method gives me an int which can be cast to a
char showing the text that the stream contains.

package com.cpsoft.console;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;

public class ConsoleInputStream extends InputStream
{
    private StringBuffer buf = new StringBuffer();
    private int pos = 0;
    private JConsole con;
    public ConsoleInputStream(JConsole c)
    {
        this.con = c;
        synchronized(con)
        {
            EnterAction act = new EnterAction();
            con.input.addActionListener(act);
            con.enter.addActionListener(act);
        }
    }
    public int read() throws IOException
    {
        while(buf.length() <= pos){}
        return buf.charAt(pos++);
    }
    private class EnterAction implements ActionListener
    {
        public void actionPerformed(ActionEvent e)
        {
            synchronized(con)
            {
                buf.append(con.input.getText() + "\n");
            }
        }
    }
}
