	  - pty and telnetd have a new subdir rtems_telnetd to avoid
	    the side effect when ftpd change.
	  - the tcp/ip stats have been implemented into icmds.c and
	    started when telnetd daemon is started.
	* rtems_servers/telnetd.c, rtems_servers/telnetd.h: Removed.
	* rtems_telnetd: New directory.

+/*
+ *
+ *  The telnet DAEMON
+ *
+ *  Author: 17,may 2001
+ *
+ *   WORK: fernando.ruiz@ctv.es 
+ *   HOME: correo@fernando-ruiz.com
+ *
+ * After start the net you can start this daemon.
+ * It uses the previously inited pseudo-terminales (pty.c)
+ * getting a new terminal with getpty(). This function
+ * gives a terminal name passing a opened socket like parameter.
+ *
+ * With register_telnetd() you add a new command in the shell to start
+ * this daemon interactively. (Login in /dev/console of course)
+ * 
+ * Sorry but OOB is not still implemented. (This is the first version)
