Telnet access to the Vocality console

Vocality products include a supervisor function, which provides a simple menu for
management and configuration of the device. The supervisor is accessible either from
the M&C or console port, or via Telnet. Navigation of the menu requires the use of the
arrow (cursor) keys, the <Esc> key and several <Ctrl> key sequences such as <Ctrl>
<E>. The default terminal type used by the supervisor is VT100.

5.8.2.1 Standard Telnet

Most Linux distributions will provide a Telnet client, but these may not emulate a VT100
terminal and will not necessarily allow use of the arrow (cursor) keys or other special key
sequences.
Many distributions default the terminal type to 'linux' or 'xterm'.
In order to change this to VT100 and then start Telnet, you will need to type the
following:
export TERM=vt100
telnet hostIPaddress
It is sometimes necessary to type <Ctrl> <E> followed by <Enter> several times
before the cursor keys will respond as desired.

5.8.2.2 C-KERMIT

Although it is possible to customise Telnet to work better when connecting to Vocality
devices, a more satisfactory method is to use C-KERMIT which is a powerful
communication program supporting scripting and much more. C-KERMIT is freely
available for most UNIX derivations including Linux.
Once C-Kermit is installed, create a file .kermrc in the user's home directory and copy
the following lines into the file.
SET TELOPT AUTHENTICATION REFUSE
SET TELOPT KERMIT REFUSE REFUSE
SET TELOPT NEW-ENVIRONMENT REFUSE
SET TELOPT NAWS REFUSE
SET TELOPT FORWARD-X REFUSE
SET TELOPT COM-PORT-CONTROL REFUSE
SET TELOPT AUTH REFUSE
SET TELOPT TERMINAL-TYPE REFUSED
SET TELNET BINARY-TRANSFER-MODE OFF
SET TELNET NEWLINE-MODE OFF
SET TELNET TERMINAL VT100
SET TELNET ECHO REMOTE
SET KEY \127 \8
These last two commands suppress local echoing of keystrokes and map the
<Backspace> key to send ASCII BS instead of the default RUBOUT. Without these
changes you will not be able to type commands in the debug or TTY modes.
Now issue the following command to connect to the Vocality device:
Kermit –J vocalityIPaddress
