Hi
I am configuring a 2511 as a terminal server. I have two 2511s. One 2511 is OK. The other one gives me an error when I try to paste the same configuration that I have in notepad.
For the command:
line 1 16
modem InOut
it says that, "line 2 does not support modem control"
Then I typed:
(config)#line 0 17
(config-line)#modem InOut
it says, "line 0 does not support modem control.
Now it doesn't talk about line 2, instead it says that line 0 does not support modem control.
In here, the main problem is that, when I type:
(config)#line 1 16
(config-line)#no exec
and when I telnet, the router doesn't even prompt for anything. But when I again say, "exec" in line mode, then the router prompts me for the username.
But when I enter the username, it says:
traying 192.168.1.1, 2001.....
Destination unreachable; gateway or host is down.
Below I will paste the configuration that works in the other 2511 router.
line con 0
logging synchronous
login
transport input none
line 1 4
session-timeout 20
no exec
exec-timeout 0 0
no flush-at-activation
logging synchronous
modem InOut
transport input all
line 5 16
session-timeout 20
no exec
exec-timeout 0 0
no flush-at-activation
modem InOut
transport input all
line aux 0
password xxx
logging synchronous
login
line vty 0 4
exec-timeout 20 0
logging synchronous
login local
line vty 5 15
exec-timeout 20 0
logging synchronous
login local
!
In this setup, I have a loopback interace configured. Basically, everything is OK. The only difference are these two commands don't work like in the 1st router:
no exec
modem InOut
A very confusing scenario.
Any help on this would be highly appreciated.
Thanks in advance!

Response marked with
line 1 16
modem InOut
it says that, "line 2 does not support modem control"
line 1
modem inout
then try line 2 and so on and see if we see errors for specific lines only (which we can investigate further)
(config)#line 0 17
(config-line)#modem InOut
it says, "line 0 does not support modem control. Now it doesn't talk about line 2, instead it says that line 0 does not support modem control.
(config)#line 1 16
(config-line)#no exec
and when I telnet, the router doesn't even prompt for anything. But when I again say, "exec" in line mode, then the router prompts me for the username.
A few things to check:
1. Is the router completely up, means its not in boot mode etc.
2. Are the IOS images different or same on the working vs non working 2511?
Thanks, Mak

Hi Mak
Thanks a lot for your post.
I tried giving line by line and started with
line 1
and pasted the configuration
session-timeout 20
exec-timeout 0 0
no flush-at-activation
logging synchronous
modem InOut
transport input all
Then I tried
line 2
then I got the same error.
About 'no exec'
in line 1 16
when I say:
(config-line)#no exec
I can't even telnet to the router. Not the reverse telnet. But the moment I remove it and say, 'exec', then I can telnet and login to the router.
With 'no exec' when I go to DOS prompt and telnet, it tries to telnet, and it is suppose to prompt me for the username (because in line vty, I say, login local, and I give a username and password in global mode) but nothing prompts and the screen closes in a few seconds.
Yes the router is functional. And it has exactly the same IOS as the other one which is working without any problems :(
A really terrible situation.
Thanks a lot in advance for your help!
