Thanks phil,

This is my situation.

I have about 20 network devices to manage.

Whenever there is some common change in setting, I have to log on to each and every device and reconfigure.

What I am trying to do is (cos i'm lazy), I want to create a script to automatically log in to a device and execute commands and then log off and login to the next device .. etc .. all auto.

So using batch file, I am able to start telnet. BUT as I learnt over the past few days, DOS is not optimised for interfacing with devices (thanks ASBO). Thus I cannot execute telnet commands.

So I also tried Hyperterminal. You can prepare text files with the necessary commands before hand and after logging in to a device, let the file run. It is WAY faster than typing by hand all your usual commands.

However, I still have to create a new connection each time. I want to automate that too.

Currently I am researching telnet clients with scripting facility. CRT is popular in my office, however it has limited scripting ability. Then I found TN 3270 yesterday. It seems to be meeting my expectations, but I haven't wrote the script yet.

I'll welcome any suggestions. Thanks.
