Always leave either the console port or aux port available in a test
situation. You can learn everything you need to know by playing with only
one of those two ports at a time. Once you have figured out how to get
around it (look in the archives) then lock yourself out of both ports
simultaneously...
If your routers are connected over a network you can telnet to them and do a
clear line on them. If not, you need to either get into the console or aux
port somehow. If you can't -reboot.
