These are typical lasers. No sharks are involved. Well you never know if some new transceiver HW had been created capable of some fanciness, but apparently no -- no sharks. :) <cb> Not yet! --cb Thanks, Chris. > > Power-sleep is a software state to describe an interface that is intentionally > shut off and can be reactivated when demand arises.
