you'd think i'd know by now that powercycling one particular box of
mine will always kill the egress router. i never learn. it took me
about a year of "wtf?!" to actually get used to remembering that
powercycling the box with the serial console on it will send a "break"
to the router and i need to boot as fast as possible, tip in, and "c"
later i just pulled the cable off. it was easier and i ended up
accessing the router less than i was rebooting it because i hadn't
recalled yet exactly what i'd done wrong. brain slow.
but i can also appreciate the statement from the angle of one who
plugs and unplugs sun keyboard cables as well: that's also a break
signal. at least...until we upgraded to e450s and left the keys
(removed, but) in the locked position so that the machine would ignore
the standard set of break signals.
