[14] WHY DO I GET DOUBLE PROMPTS OR DOUBLE RETURNS WHEN I TELNET HERE?

     If you're asking this you are probably using Windows 2K or XP.  The
     easiest solution is to not use Windows TELNET, but use a free SSH
     client such as 'putty' or to connect to http://sdf1.org/ssh

     If you can only use Windows TELNET, then you follow these simple
     instructions:

     1. Escape back to the TELNET> prompt by pressing CTRL and your ] key.
     2. type 'unset crlf' 
     3. press return TWICE to return to SDF.
