When I power-on a 3640 Router with no adapters installed, all I see in Hyperterminal is a repeating "C" across the screen. What does this mean? I pulled this router from a storage room to see if it is working. It has two RAM and to FLASH SIMMs installed. I tried Ctrl+Break to go to ROMMON, but no luck. If I leave it, the characters eventually stop and nothing happens. Thanks.
Yes it is certainly possible that the speed of that particular router is set differently. That is what I was suggesting.
I found a link about the console speeds of the 3600 router which might be helpful. In the article is this:
you see that there are eight possible console baud rates, namely, 9600 (default), 4800, 1200, 2400, 19200, 38400, 57600, and 115200 baud. If you do not know the console speed of the router, it is difficult to set up a hyperterminal session with the correct speed. A solution would be to just try the eight possible console speeds above and see which one works.
