I have a 2811 with 16 serial lines for reverse telnet to my labs. I have 10 devices consisting of 4 switches and 6 routers. I can connect all devices except one. I have tried changing the octal cable, re-configuring the 2811 and even replaced the end router. The connection comes up initially but after a few lines it locks. I thought it may be a flow control problem but all lines are set to none.
Has anyone experienced this problem before and if so how was it resolved ? I have attached the configuration of the terminal server.

Does the problem track the port, or the device?
For example, if you swap the device on the failing port with a working one, do you get the same behavior on that port, or does the problem follow the device?
If the device, what is the device that is causing the problem? How long is the physical wire to that device?
