The ISR 1100 doesn't have an AUX port but from what I can tell, you can utilise the Console port to provide the functionality normally associated with the traditional AUX port.
Is it possible to configure reverse telnet on an ISR 1100? I've tried but without any success. For example:
int lo0 ip address 220.127.116.11 255.255.255.255 ! line con 0 no exec modem InOut trans in telnet trans out none
The LED on the console port changes from Green to Amber as expected but nothing listens on TCP/2000 ("sh ip socket" confirms this). I just get a "connection refused".
I can't find anything specific to the ISR 1100 or 1000 or even 4000 series with regards to reverse telnet. Is it possible? Am I missing something?

Thanks. I had came across that yesterday and even though I'm not using a modem, I did try this configuration but the router still isn't listening on TCP/2000, TCP/2001 etc. Not sure if it needs to detect a serial signal before it'll start the reverse telnet server. I'll try again today and if I still don't have any luck I'll try TAC.
