I have got 2811 router that is connected to analogue modem (56000), and my PC is connected to another analogue modem (33000)
The intial configuration for the router was :
Router2811#show run | begin line aux
line aux 0
exec-timeout 20 0
password xxx
logging synchronous
login
modem InOut
stopbits 1
flowcontrol hardware
Router2811#show line

It did not work when remotely I tried to login to the router !!! it kept disconne
What I did was this :
Router2811#config ter
Router2811(config)#line 1
Router2811(config-line)# modem autoconfiguration discovery
The router automatically discover modem's speed 115200 and replaced the 9600 in the configuration above.
Router2811#show run | begin line aux
line aux 0

Now remotely I was able to access the router.
But when I tried to reduce the speed from 115200 to 56000 (modem speed), my modem got disconnected and then I reduced the speed to 9600, but same problem happened ( modem got disconnected ).
Modem got disconnected after I received these funny characters :

Hi,
If you dont mind which make and model of modem are you trying to use here. I was stuck in a similar situation a couple of months ago.
I was trying to use USR with 8 dip switches and it never worked, however when changed to a normal modem it worked!
If the router is able to discover the modem then there shouldnt be much issues.
Let us know even if the problem persist even if you change modem

What I did is this :
I dropped the PC's speed from 115200 to 57600,and it worked without seeing funny characters.
I have not touch the speed on the router side, I left it as it is.
What be the case if I reduce the AUX's rooter speed ? When I tried to change it by doing this :
Router2811#config line 1
Router2811(config-line)#speed 56000
Failed to ,,,,,,I do not remember right now
Why it gave me failed error message !!!!!
Thanks
