Communicate with another host using the TELNET protocol. host may be either a name or an Internet address (dot format). telnet has a command mode (indicated by the telnet> prompt) and an input mode (usually a login session on the host system). If no host is given, telnet defaults to command mode. You can also enter command mode from input mode by typing the escape character CTRL-]. In command mode, type ? or help to list the available commands.
