Is there a machine near the thing that you want to switch?
I solved this by connectiong the input of a solid state relais to the
DTR line of a terminal server. If I connect to the serial port DTR
becomes active, switching power on via the solid state relais. When I
disconnect DTR gets droped and the power is shut off. You need a solid
state relais because the DTR line doesn't deliver enough power for a
mechanical relais.
