I need help config a 2509 as a terminal server!

Serial0

Hey folks! I need a sanity check on configuring a 2509 (w/octal cable) terminal server as it just "hangs" upon telnet:

R2509#telnet r1 2001
Trying r1 (10.10.10.1, 2001)... Open

I tried hitting the "Enter" key there afterwith no console access to the target device (target devices verified accessible directly with hyperterminal com to console port access). The only key combo that works is the ctrl-shift-6 x sequence:

R2509#clear line 1
[confirm]
[OK]

Here's my config and some show outputs:

I've reviewed cisco's pdf and wildfire's config:

Hopefully, someone can help pinpoint my problem

I'm using the same config as wildfire on my 2511 and that works fine.

I tried your config on my 2511 -- and it still worked fine (but I didn't clear my config or reload, so something in my running config still could have been there....).

Are you sure you have the right cable plugged in? Some of my octopus cables have labels glued on that are easy to read, others are molded into the end and are hard to find, let alone read.

After you telnet and escape back to your 2509, what does show line show for the line?

Thanks for checking my config on your 2511! I tried the remainder cables 2-7 as suggested just in case they were mislabled with the same results.

I swapped back to cable 1 and powercycled the target device. I observed the boot sequence followed by the link status come up! However, it doesn't go beyond the link status nor doesn't it respond to keyboard inputs.

Here are the last few lines followed by the "ctrl-shift-6 x" sequence and show ses output:

I believe that means the cable (good/bad assumption?) is ok but I am still unable to get a response from the target when I hit the "Enter" key...

Hrmm.. if the config on the 2509 is assumed to be correct and cable 1 is fine, then that may mean I need to take a closer look at either my putty configs or the console configs of each target... grrr..

Opps, forgot this show output:

I had a similar issue with just 2 of my routers. This was down to them being older than the rest of mine and requiring different console settings. I cannot remember exactly now, but under those specific lines I had to enable hardware flow control and changed something else! Sorry I cannot remember what exact settings. I don't have access to it right this second.
