If you enter the command without arguments, telnet enters command mode and displays the Telnet

prompt. After connecting to the remote host, telnet prints a message called a connect banner, which

displays the Telnet escape character. If pressed, the Telnet escape character returns you to the telnet

prompt, where you can enter telnet commands. For example:

annex: telnet topsy

Connected to topsy

Escape character is "^]".

After establishing the connection, telnet is in input mode. Input mode supports either

character-at-a-time or line-by-line mode. In character-at-a-time mode, the Model 5390 server

immediately sends each typed character to the host, where character echoing and line editing occur.

In line-by-line mode, the Model 5390 server retains input until you press either Return or an

interrupt character. In this mode, character echoing and line editing are performed locally at the

Model 5390 server. Using the telnet mode command, you can change both the mode and where

echoing occurs.

You can send a Break to the remote host by using either the regular break or the long break key.

This allows you to send a Break sequence using a local break, rather than using the Telnet send

brk command. To do this, you must turn off the regular and/or long break as the CLI attention

character (see stty on page C3-62).

If a foreign port is not speciﬁed, telnet defaults to port 23. The local port is chosen to represent the

user location as follows:

If the user connects to the Model 5390 server via a serial port through a modem or a terminal,

the local port is chosen as 10000 + port*100 + sequential, where port is the serial line number

(1 to 99), and sequential is a number (0 to 99) that distinguishes connections, and is chosen

sequentially.

If the user connects to the Model 5390 server via the network, by using telnet annexname, the

local port is chosen as 10000 + sequential, where sequential is a number (0 to 99) that
