Hi. I just recently bought a new Cisco 2611 for my home lab and am having trouble getting the serial port to work. I have tried multiple things such as erase startup, switching the cables to rule them out, and even changing IP addresses but none worked. The port may be dead but I thought I would see if anyone could see anything else to try before I replaced it. Here is the output I am getting:

This is the serial cable I am using. Yes I am connecting it to another router. I have tried both ways but currently have the DCE end plugged in to the port I suspect is not working. I have narrowed it down to this port because when I use the serial port on the second router connected to a third, it works.
