cat & telnet

cat & telnet
hello,

I need some help on using a file with the cat command. I want to set up a telnet connection with a network device with the ip-adress 10.3.0.1. Just executing the command 'telnet 10.3.0.1' gives a menu. For example, to show the help of the menu, you need to type '?'.

Now I want to go through the menu with commands (like '?') that are in a file. For this I want to use the command:
cat filename | telnet 10.3.0.1

When I try this, the telnet connection is established, but then it closes immediately afterwards. So I suppose something's wrong with the file. But I have no idea what the file should look like. For example, do you need to mention the enters after a command in a certain way?

just to be clear: the command in the menu that I want to execute are:
"?" -> enter
"projector" -> enter
"exit" -> enter

thanks in advance,

Micha�l

telnetrc

telnetrc(4)						     Kernel Interfaces Manual						       telnetrc(4)

NAME

       telnetrc, .telnetrc - Specifies setup commands for a telnet session

SYNOPSIS

       $HOME/.telnetrc

DESCRIPTION

       The .telnetrc file contains the setup information for a telnet session.	It is a hidden file in your home directory and must be readable by
       the user logging in.

       The file can consist of multiple entries for each remote host to which a user can connect.  A remote host entry consists of multiple lines.
       The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands.	These sub-
       commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines.	See telnet(1)  for
       a complete list of telnet subcommands.

       To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub-
       commands in the subsequent lines.

EXAMPLES

       The following shows a sample .telnetrc file:

       # Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT
	  environ undefine USER # First system entry system1
	  set echo
	  toggle crlf # Second system entry system2
	  set echo
	  mode line
	  toggle crlf

FILES

       User-customized telnet startup values.
