_________________________________________________________________
telnet <nodename>|<ip_address> [<port_number>]        Default: 23
_________________________________________________________________
The 'telnet' command allows you to initiate a connection using
the Telnet protocol.

The command creates a Telnet session to the specified host.  With
the default port number (23), a connection is made to the Telnet
server at the remote host.

If the remote host is running a KA9Q NET Telnet server (i.e. the
host has issued the command 'start telnet'), you will be 
connected to the built-in KA9Q BBS on that host.  

To access your own built-in KA9Q BBS, start your Telnet server
(with 'start telnet'), then give a Telnet command to your own
IP address.  (N.B. You must also ensure that you have an account
specified ib ~/ftpusers).

Use the <F10> key to escape from a Telnet session back to command
mode.

Use 'close' to close the connection.

If a remote host requests a Telnet session, a message similar to
the following will be displayed on your screen:

    Incoming Telnet session 2 from 158.152.123.251:1026

If you are in command mode, enter ENTER at a "net>" prompt and
you will enter converse mode for the Telnet session.

If you are in converse mode, use the <F10> key to escape back to
command mode, use the 'session' command to list the active
sessions, and then use the 'session <session_number>' command to
enter converse mode on the desired Telnet session.

The Telnet session can be recorded to a file (using the 'record'
command), or an ASCII file can be uploaded instead of entering
the information at the keyboard (using the 'upload' command).
