I was able to score an old Cisco 4000 router for free that I hope to use as a training tool. It seems to use to require a null modem cable (25 pin to 9 pin) for a terminal connection (as opposed to the rj-45 to 9pin serial that the newer routers use). I've tried a null modem cable and I'm not getting a Hyperterminal connection (using 9600 Baud, no parity, no flow control, 8 data bits, 1 stop bit). Does the 4000 require a special cable for terminal connections or am I just overlooking something? I've double checked that the serial port (COM1) is enabled, etc.
I can't telnet to any of the Ethernet ports, because I have no idea what their IPs are. I also believe that you need to use the console to reset the password, etc. Any help is greatly appreciated.
