if it's not $0, I can't get it at work. apparently $10B in cash on
hand is not enough even though it would provide payroll for 2.5 years
with $0 revenue the whole time.

We have some console servers but the software they run on (don't ask)
is totally unsupported for security fixes and we can't use them any
more unless we upgrade the firmware to a newer version and that
conflicts with the $0 issue :-\



, get a console server. Allows you to connect serial devices to a network.

James P. Kinney III

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
