What method are you using to control your cable box? If you are using
an IR blaster, then that may be the best you can do--keep toggling power
until you get data. If you are using firewire, then it should let you
send a status command to check if the power is on, and you should have
separate power on and off commands, as well as a toggle. Of course,
some boxes have firmware that doesn't support all of those commands, so
you might be out of luck (e.g., if you have a Verizon Cisco box, the
status command will work, but you'll need an IR blaster to send the
power command).
If your cable box supports it, firewire is usually the best way to
control it.
