871 console port not working

I have a 871 router and trying to get the console to work.



I tried pluggin in the blue Cisco console port cable into the combined console port/aux port on the back of the 871, I get garbage characters in the hyperterimal that I'm using to connect to.



I can plug the same cable using the same setup into a 3825, 1811, 2811 and they all work fine and I can login etc.



I tried the reset button on the back of the 871 but apparently all it does is if it's pressed within 5 seconds of boot and there is a valid alternative *.cfg it will use that rather than startup but that didn't help.



Anyone have any ideas ?



Thanks



John

Try messing with the speed, databits, parity options on the machine you are connecting with.

I went through tons of combinations etc etc.

Went from 1200 all the way to 115200 and it finally worked !

So 115200 8-N-1 works if anyone gets their Aux - console port on a 800 series to stop working.

9600 8-N-1 is the default so either you or someone else had to have changed it at some point.
