I have 3 devices with cascading consoles
R1 --> R2 --> R3
I connect from R1 to R2 using reverse telnet.
Then I make a second reverse telnet from R2 to R3.
When I make the usual ctrl-shift-6 x, the link between R1 and R2 gets disconnected, but the R2/R3 remains active, no matter what the exec-timeout.
when reconnecting, i land directly on R3, and R2 is unreachable.
I cannot telnet to R2 directly, to reset the aux line.
How can I get to R2 again? (Physically resetting is not an easy option, since there are no operators.
