Hello:
I never knew a Cisco 3640 router can act as a terminal server. I am confused.
When I telnet to this terminal server device in the lab, this is the configuration I see.
testlab#sh run

I do remember the old Cisco 2511s that had a dozen or so ASYNC ports to which you would connect the console ports of the devices you want to access remotely.
I dont see any such interfaces on this 3640.
Any thoughts?
Thanks

I am trying to find a link to a Cisco page that will explain that configuration above. I mean the "menu......" jazz that dictates what the output is that the user will see when telneting to the box.

Victor,
This portion is the terminal server connection:
line 33 64
session-timeout 20
flush-at-activation
no exec
transport input telnet
transport output telnet
autohangup
Here is more information on Terminal Server on 3600 Series router:

Thank you very much, my friend. That helps a lot. I see then that the 3640 is using an NM32A virtual ASYNC module that uses a high density connector cable with RJ-45s on the other end ( a spider cable, as we used to call them). Got it.
