Nope! You need the password. If you don't have it, you can't get on. You will have to contact whoever installed the POS terminal and get it from them.

I wouldn't use telnet to contact the POS unless the POS was within a secure network. Telnet sends everything "in the clear". There is no encryption. User names and login passwords are sent in the clear. So unless you are looking for your POS's to be compromised, DON'T USE TELNET.

Good luck. Without the password you are wasting your time.

Learn ssh. There are several free ssh clients that run very well on Linux. Even set up a very nice ftp/copy interface. ssh is secure. User logins and passwords are sent encrypted.

Why don't you dump the script that you have written so far?

Can you get the script to work if you put the password in the script? Like

PASSWORD=password
telnet ..... $PASSWORD

You might have to put the entire telnet and commands in a "here" document. And cat the telnet responses into telnet.

This is a snippet from a mass mail client I have:

cat << EOF
From: $RETURNADD
Subject: $SUBJECT
To: $REC
EOF

The "here" part is from EOF to EOF that is "cat"ed . (from here to here)!!!
