NM 16-A Module

I faced with a problem in a solution as follows :

+ The task is about using a module NM 16-A ( It is Not NM 16-A/S ), to obtain a console connections from a Router 2811 to another Router 2811 too.

+ I used a Configuration from Cisco site , Using this URL :

But it did'nt work , it gave me (( Connection refused by a remote ... ))

when I put the router hostname , or ip and port no

+ I put these configuration as follows:

Router (1)

ip host 3640-1 2001

ip host 3640-16 2016

ip host 3640-15 2015

ip host 3640-14 2014

ip host 3640-13 2013

ip host 3640-12 2012

ip host 3640-11 2011

ip host 3640-10 2010

ip host 3640-9 2009

ip host 3640-8 2008

ip host 3640-7 2007

ip host 3640-6 2006

ip host 3640-5 2005

ip host 3640-4 2004

ip host 3640-3 2003

ip host 3640-2 2002

interface Loopback1

ip address

line 1 16

session-timeout 20

no exec

exec-timeout 0 0

Router (2)

I Did'nt add any configuration except the enable password and the enable secret .

+ The questions is :

- does there is any additinal configuration ,which I must add to make the system work ??

- could I add some configuration to the second router to change the situation ??

- Does any of you have any good documents helping in this situation ???

Please it is Urgent ,

Thank you for your help ,

what I have to do


Re: NM 16-A Module

If a raw TCP stream is required, the port is 4000 (decimal) plus the decimal line number. The raw TCP stream is usually the required mode for sending data to a printer.

I could be wrong but from very long ago I remember having done this using ports in 4000 range.
