Creating Terminal server with IR1101

We're trying to create a terminal server to be reached over cellular.  We have an IR1101 with an attached IRM-1100-4A2T, offering 4 Async ports 0/4/0 through 0/4/3.  Going through the documentation, I have created the following configuration to reach a switch's console port through as0/4/0, but it doesn't seem to be working, and I don't really know where to go from here.  When I telnet to the loopback on the port, I telnet into the router instead of bringing up the console port connected to the switch.  Any direction would be appreciated.

interface Loopback0
 description Management interface
 ip address 192.168.1.1 255.255.255.255
 
interface Async0/4/0
 no ip address
 encapsulation relay-line
 media-type rs232
 
line 0/4/0
 transport input all
 transport output all
 speed 115200
 
relay line 0/4/0 0/0/0

ip host SWITCH 2002 192.168.1.1

you need to telnet/ssh to the management ip-address, not the async 0/4/0 
then you need to modify the port in the connection, not using 23 (default)
but <base> + <line-number> or <base> + <line-number> +1
if base is 1000  (need to lookup the base number for this router)
then it will be like
     telnet 192.168.1.1:1098
to
     telnet 192.168.1.1:1101

this document 
Cisco Catalyst IR1101 Rugged Series Router Software Configuration Guide - IRM-1100-4A2T Expansion Module [Cisco Catalyst IR1100 Rugged Series Routers] - Cisco

shows the table below, which suggest you can alter the portnumber used per interface

NB! this example is not describing the use as a terminal-server, but as a remote serial connection between two routers
I suggest you try the "raw-socket tcp server .... " command and connect (telnet/ssh) as mentioned in previous post but with the self specified port-number
