Unable to open COM1?

when trying to use hyper terminal and connect to the router (windows 2000), it says "unable to open COM1. please check port settings."

my question: where can I check my port settings and what then?
Update: and yes, everything is connected correctly.
Update 2: I've also tried all the other port settings listed.
Update 3: also, i checked the bios and it can see the com port.
