ChrisA If you have the time; Using communication software, you can control a modem to call, hang up, and call again every few seconds. Since you can make a phone do the same thing, there is most likely a way to get those lights to respond the same way, at least by next Christmas. jd -- http://mail.python.org/mailman/listinfo/python-list

Yes, I understand that, I was wondering whether the power could be toggled. Hmm. Can you control whether a particular port is on or off?

So far as I can tell Windows doesn't let you turn the ports on and off. I found some suggestion that by connecting it to a powered hub it may be possible to toggle the hub power on and off but that many hubs don't bother implementing the functionality. Thanks anyway. -- Duncan Booth http://kupuguy.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list

Or you might have more fun if you cut off the USB plug, and drive the thing directly using an Arduino board. You can use the USB serial port on it to prgrammatically turn the thing on and off from your computer, or a billion other possible things. -- http://mail.python.org/mailman/listinfo/python-list
