Connect the cable to the back of the router in the MGNT port and then to the back of your computer to COM 1.
Open Hyper Terminal and create a new connection, set it as follows, 1: Name the connection Cisco, 2: Ignore the first three fields and in the third "Connect using" set it to COM1. Click ok.
Set Bits per second to 38400, Data Bits 8, parity none, Stop Bits 1, Flow control None. click ok.
Then your Hyper Terminal Session screen will pop up. Hit Enter.

What happens if you first do a "set nvram erase" then a reboot and then resetup your full configuration? What is your full configuration?
