telnet - user interface to the TELNET protocol
The telnet command is used to communicate with another
host using the TELNET protocol. If telnet is invoked

indicated by its prompt ( telnet>). In this mode, it
accepts and executes the commands. If it is invoked
with arguments, it performs an open command with those
arguments.
