-# Minimal interface to the Internet telnet protocol.
-#
-# *** modified to use threads ***
-#
-# It refuses all telnet options and does not recognize any of the other
-# telnet commands, but can still be used to connect in line-by-line mode.
-# It's also useful to play with a number of other services,
-# like time, finger, smtp and even ftp.
-#
-# Usage: telnet host [port]
-#
-# The port may be a service name or a decimal port number;
-# it defaults to 'telnet'.
