I don't always get the same results when trying to exit a telnet session, a traceroute that is timing out etc.
My understanding is the official way is to: hold down three keys all at once ctrl-shift-6 and then release all keys and hit the x key.
It seems that once will not always exit and I must repeat this several times.
I also remember just holding down ctrl-shift-6 and releasing all keys. Do this several times and the router takes me back to the prompt.
Am I just imagining this?
