Post the output of 'show ip route' on router 3. That would make troubleshooting a lot easier.

set your PC1 default gateway to 192.168.1.1 ; )

You have both ends of your serial connection setup as DTE. You need to set one side up as DCE and indicate a clock rate on that side.

I guess that should be it. You need clocking on one end because, technically, you can't ping a 'down' interface. and a serial interface will always be 'down' unless there's clocking on one end.

If that isn't the problem (and you mistakenly wrote DTE instead of DCE on your post) then you might have a cable issue or your serial interface might just be adminisratively down.
