Blinkenlights?

["Engelen" <engelen@hotpop.com>]

Hello,

I had this cool idea the other night: wouldn't it be (fairly easily)
possible to create a little component with som LED's which shows the status
of some serial port, so you could write some programs to do the following:

~$ ledoff green; someprogramthattakeslong; ledon green
(switch the green led on when the program is finished)

Or maybe 3 leds (red,orange,green) to show memory/cpu usage?

I think this would be really cool. Anyone some pointers how this would work
or why this cannot work? Where should I look for info? I don't want to kill
my serial ports :)
