Hi there
I have a USR5686E modem and a cisco 2800 router.
I would like to configure the router through the console port by dialling into the modem.

Would the command syntax in this guide:

http://www-tss.cisco.com/eservice/compass/common/tasks/task_verikit_configure_USRmodem.htm

work with my modem, too? or is this for older usr modems?

Yes, it should work for any USR modem

but the instructions you have specified in one of your posts are different from the cisco ones.
do you say that both would work?

can you confirm if a CAB-500RJ= cable is a rolled cable or not?
the reason I'm asking is that, I have a grey cable marked CAB-500RJ= which came with a router, and it's NOT a rolled cable, it's a straight through cable.

This is the init sting that I use for USR modems (cut/paste directly from here)
ATE0F1Q1&I0&H0&K0&A0&B1&N6&C1&D0&W0

CAB-500RJ=
Looks like this is a standard network cable, not a rolled cable. The rolled cables are the flat ones that are either baby blue or black and come with most every Cisco product.
You might have to find the right 25-pin/RJ-45 adapter to connect to the modem.

ok I found the right cable and the right adapter, and a very interesting thing happens:

when the modem is connected to the router via the rollover cable, the modem auto answers for 1 second only and the line drops!
when the modem is connected to the router via a standard straight through network cable, OR when it's not connected to the router at all, the modem autanswers ok and establishes a connection.
after the connection is established, if you connect the rollover cable between the modem and the router it's possible to access the router through the console port! what do you make of this?

Sounds like maybe not the right 25-pin adapter..
Did you add any configuration to the router on the console line?
Did you set Hyperterm to only connect at 9600?

Which init string did you use? The one in the first document, or the one I posted?
Can you compare ATI4 output to the below, which is correct and working modem:

B0  E1  F1  M1  Q0  V1  X4  Y0    BAUD=9600  PARITY=N  WORDLEN=8    DIAL=TONE    ON HOOK   CID=0     &A3  &B1  &C1  &D0  &G0  &H1  &I0  &K1    &M4  &N0  &P0  &R2  &S0  &T5  &U0  &Y1

They don't quite match what I would expect. Does this modem have the dip switches on it? Did you follow the dip switch setting procedures?

                                       X4  <== I have X4 (could be different model # modem)
