Are you referring to the physical device serial number or to that software serial number? If you know both and are wanting to check their validity, that can be done by contacting customer supprt at Cisco.

Phew! It worked. Thanks a zillion.

Please how do I verify a Serial Number of an item?

Check your communication settings in hyper terminal.

If the router is not configured, you need to connect to the console port using a serial cable.
HyperTerminal needs to be configured with the right comm settings.
If I remember right, it has to be 9600 bits/sec, 8 data bits, no parity, 1 stop bit and flow control – none.
If I have the wrong settings, I’m sure everyone else will keep me honest.

Initially you will probably configure your router from a terminal. If the router is already configured and at least one port is configured with an IP address, and it has a physical connection to the network, you might be able to telnet to the router and configure it across the network. If it is not already configured, then you will have to directly connect to it with a terminal and a serial cable. With any Windows box you can use Hyperterminal to easily connect to the router. Plug a serial cable into a serial (COM) port on the PC and the other end into the console port on the Cisco router. Start Hyperterminal, tell it which COM port to use and click OK. Set the speed of the connection to 9600 baud and click OK. If the router is not on, turn it on.

If you wish to configure the router from a Linux box, either Seyon or Minicom should work. At least one of them, and maybe both, will come with your Linux distribution.

Often you will need to hit the Enter key to see the prompt from the router. If it is unconfigured it will look like this:
Router>

If it has been previously configured with a hostname, it will look like this:
hostname of router>

If you have just turned on the router, after it boots it will ask you if you wish to begin initial configuration. Say no. If you say yes, it will put you in the menu interface. Say no.

Hope that helps.

Thanks so much, mpkn3rd . I greatly appreciate. I did all that, but the HyperTerminal wont pull down the configuration, so, I guess the router is bad then. Or is there anything else I need to do? I started the HyperTerminal, powered on the router, and clicked on ‘connect’, yet, nothing. Please help.
Thanks.
