hi,
Our system with Windows 2000 server. System connected with out Mobile operator through Frame Relay connection. In order to this Cisco 1600 series router connected through Console Port.
Now we have to configure our router with new IP Address,Subnet Mask,Bandwidth etc. When i try to connect router using HyperTerminal, it is giving error "Unable to open COM1. Please check port settings."
In the device manager it is showing that, COM1 is working properly.

How i can trubleshoot this? What options i have?

Check to make sure that no other applications on the server are using COM1.
It could be some application or a service running in the background.
I'd suggest using a laptop or other system to access the console of the router since it might be inconvienient to reboot the server just to get the com port to open.

Not the solution you were looking for? Getting a personalized solution is easy.

You can telnet to the router. Which interface are you changing, the WAN or the LAN? Sounds like a WAN interface. No problem changing that from a telnet session.
