Router does not respond in console

Router does not respond in console open original image

I just got three used 2501 Cisco routers and am trying to connect to through the console. I had a RJ-45/DB9 cable hooked up, fired up Hyperterminal, and turned on the router. I see all the bootstrap messages but it does not respond to any of my keystrokes. I've tried each router thinking the first one may have just been defective, but they all do the same thing. My settings in Hyperterminal were 9600-8-n-1. I tried it with XON/XOFF, Hardware, and NO flow control but nothing worked. My current thought is that there is still some Hyperterminal setting I need to change or there is something wrong with my consle cable (but then why can I see the router output?). I'll paste the Bootstrap below. I hope someone can help.



Thanks.

One more note. I found this thread that seems to state that console ports get partially fried when hooking them up to an ISDN line and then I may get the problem I have now. Someone suggested using a NULL modem adapter or breakout box. I have neither at the moment and would like to get this working soon without having to acquire one of these things. So I just snipped PIN 1 on my console cable. Nothing changed. I can still see bootstrap but no response from the keyboard.

Thanks. Here is the link to that thread:

Hook your console cable to the AUX port and try that and make sure the config-register is set to 0x2102.

This was actually a very simple problem. My DB9 to RJ45 cable just had the wrong pinouts. When I built the cable from scratch everything worked fine.
