Hello,
I am having some problems with my serial connection to any 7200 series router. It seems that the console text shows up fine, but once I enter a keystroke, it sends gibberish to the screen. Example: When I press enter it will send either an "M" or an "-".... No idea what is wrong, I have tried using three or four different terminal programs and all of them produce the same results. I have also tried several different baud rates and re-installed my COM port drivers.
I find it interesting that this only occurs on 7200 routers... Everything works fine on all of our Cisco switches. Please let me know if anyone knows a cure for this.
Thanks.

What is your config register set to? This will allow you to determine your baud rate.

baud rate is 9600

Sorry, I was referring to the baud rate on the console port of the router. Look at this page for more information on setting and checking the console port baud rate setting:

Confreg is set to 2102 and baud rate is 9600. Any ideas?

are you directly connected or are you using reverse telnet?
Are you able to telnet (or SSH) to the device without getting all the garbage output?

I am directly connected to the console port via serial connection. When I telnet to the device it works fine.

I/O controller or NPE-G1/G2? If it's an IO controller I'd assume it's probably messed up, as it has to be a console port problem if you can telnet without issue. This wouldn't surprise me as those IO controllers are giant pieces of crap. (I've worked with a lot of 7200s and 9 times out of 10 the IO controller is the thing that causes issues)

I'm fairly certain the problem is on my end somehow. My buddy can console in fine via his COM serial connection.
