_________________________________________________________________
telnet <host> [<port_number>] Default port_number: 23
_________________________________________________________________
The 'telnet' command allows you to initiate a connection using
the Telnet protocol. The end result is much the same as doing an
AX.25 connect in most cases, but you'll be taking advantage of
the attributes of the TCP/IP protocols.
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 NOS Telnet server (i.e. the host
has issued the command 'start telnet'), you will be connected to
the BBS on that host. See the 'bbs' command.
Once the connection is made, you can then type back and forth
just as if you were connected with a normal TNC. When you're
done, use the <F10> key to escape back to command mode, and then
type '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 ns9ken:1026
If you are in command mode, enter CR 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).

telnet ns9liz 87 (same as 'ttylink ns9liz')
