A Cisco 2501 router was recently donated to me and I have a few questions in
regards to using the console connection.  I am new at all this and I
apologize in advance if this question seems to easy.

I am able to access the routers configuration from my computer, using the
console cable.  The router has 1 ethernet and 2 serial ports, which are not
connected to anything.  My main concern is that when I have the terminal
session open, the router seems to reboot every 15-20 minutes.  The only
thing that I see on the terminal screen is the login:

Router con0 is now available

Prese RETURN to get started.

The routers uptime is not affected.  I am not positive on this, but it seems
to happen if I dont type anything.  Is this normal behavior?

My second question is: Can I copy the config file to my computer, without an
existing ethernet connection?

Thanks in advance!

Yes this is normal.  The timeout is logging you off automatically.
No you cant upgrade/change the IOS with just a con0 connection on the
2500s.  Others yes, but not the 2500s.
Google is your friend...

Your router is probably not rebooting. It is just logging you off when 
'inactive' timeout period runs out. You can "fix" that by adding:

conf t
line con 0
exec-timeout 0 0
end

Yes, you can. Just do a 'show run' and copy configuration from the 
terminal window to notepad (or similar program) and just save it 
somewhere on your computer.
