ngazzano,
You will need a network module NM-16A or NM-32A and cable. You can also use a Cisco 2509 or 2511 router.
Then you can connect the cables on the network module of the 2600 to the console ports of all your other devices.
Then you telnet to the 2600 and then use reverse telnet to go to the console ports of the attached devices.
This is how the "online" router labs that you can buy time from do it.
I think I read about using the 2600's AUX port if you only need to connect one. Post question in the Cisco: routers forum and you might find an "undocumented" tip.
I hope this helps !!
