Hi Reza,
I had the same issues, and the "no exec" took care of it. An interesting
side note, I had several production 6509's crash on boot because they were
hooked up to a 2509 via the console ports and octal cable, but I hadn't
keyed in the "no exec" command yet on the 2509.

> Hello Group
> I have a random issue with my terminal server. I have a 2511 that I use

> an Octal cable to connect to my routers. Frequently I will see a line go
> hot
> without me having initiated a session (I see an asterisk by the line in
> 'show lines'). If I clear the line using 'clear line x' and then open a
> session to that device I will get about a hundred lines of trash thrown to

> regular prompt access to the router with no further issues. There are also
> a

> thing, but it is fairly frequent. Here's my setup on the terminal server:
> ip host r1 2001 1.1.1.1
> ip host r2 2002 1.1.1.1
> ip host r3 2003 1.1.1.1
> ip host r4 2004 1.1.1.1
> ip host r5 2005 1.1.1.1
> ip host r6 2006 1.1.1.1
> interface Loopback0
> ip address 1.1.1.1 255.0.0.0
> line 1 16
> transport input all
> exec-timeout 0 0
> flowcontrol hardware (just added this recently )
> And here's the config for one of my end routers:
> line con 0
> flowcontrol hardware (just added this recently )
> transport input none
> Thanks
