Once I figure out how to post screenshots I'll provide the information you requested. I reran my script directing STDOUT and STDERR to a file. This is what I saw in SDTERR.

Host 172.16.47.27: eof read waiting for login prompt: username:

    The above error message IS in Net::Telnet so that makes sense. However, when I run your script against a Cisco router (assuming Cisco based on the commands in your script) it works fine.

    I ran it with Net::Telnet versions 3.03 and 3.04 and against a router with Password only and User/Password prompts. Each of the 4 iterations produced the startup config printed to my screen.

    If you are connecting to a Cisco device, have a look at Net::Telnet::Cisco as that does the "heavy lifting" for you (waitfor, prompts, etc.) and makes connecting and issuing commands much easier.

    In fact, for a script using N::T::C that works, have a look at:

    Script: http://www.vinsworld.com/software/crapps.zip
    Perldoc: http://www.vinsworld.com/software/crapps.html

      I believe this particular class of Cisco Wireless routers are pretty old. They get classified as "CiscoBG" by my monitoring system. I suspect that I'm getting back some unrecognizable character that's causing the problem. In any case I'll give your suggestion and try and let you know what happened. Thanks for your help

        I've used my script to access 11xx and 12xx series standalone access points as far back as 2005. Good luck.
