Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {

    String hostname = "localhost";

    Socket connection = null;/*from   w  w w.  java2  s  .  co m*/

    Writer out = new OutputStreamWriter(connection.getOutputStream(), "8859_1");
    out.write("\r\n");
    out.flush();
    InputStream raw = connection.getInputStream();
    BufferedInputStream buffer = new BufferedInputStream(raw);
