There are DTE to DCE serial cables available for this use. Do you have the 60 pin connectors? If you do a google search on cisco serial cables you will find several vendors. The first one I checked wanted $70 for a 60 pin DTE to DCE cable. The second wanted $19. Here is their link: http://www.boxfire.com/cab60mtcbx.html

If this will only be used for lab experiments I would check out the other suggestion about using the AUX interface. You can make a cable for this yourself if you look up the pinouts. I wouldn’t use this in a production environment since the AUX port connection puts a heavy load on the CPU.

You might want to do more than just hook the two 2500s together. My home lab has a 1700 hooked up to a linux router and an openbsd router/firewall. I used modem cables and adapters to connect them. This allowed for some interesting routing experiments.

You must get your self a DTE and a DCE serial cable inorder to connect the two cisco devices.

Then you have to configure the bandwith on both devices with a encap off PPP.

With the right cable, you could even connect the two routers together using the AUX ports. We normally use ISDN for backup, but had to resort to analog modems, where we run a ppp connection if the primary link goes down. These are just connected through the AUX port.
