You can run an AGI from within your diaplan which can do anything available to the host machine. As for turning things on/off, you have several options. a) serial port control; b) parallel port control; c) attached microcontroller; d) X-10 signals. Please exuse this for going OT into home automation stuff, but in an effort to answer the original question, here goes ... a) I have often used a little program that flips the DTR & RTS signals on a serial port (independently so you can control two things). You need to turn on/off a logic state or an LED that is fine. If you need to switch a larger electical load, put a solid state relay on that pin. I have my laser printer and my pool pump controlled that way. b) Parallel port works basically the same way with the 8 output pins on the connector that can be controlled. Haven't actually done this though. Lastly, connect a microcontroller like a Parallax Basic Stamp to your server where you can write code that runs on the microcontroller and does numerous things pseudo autonomously from c) Microcontroller like the Parallax Basic Stamp series. This allows you to run a program on this little computer device (>100.00) that was "made" for I/O control. It can do all kinds of things pseudo autonomously and feed back the info to the PC. d) X10 have several interfaces for PC's. I like a little one called the "Firecracker" interface. It uses an RS232C line and can control devices by sending radio signals from it to a reciever module that is plugged into a wall socket. It then embeds the cammands you sent it into the electrical circuits in your home. Another module then plugs into the wall somewhere and you plug devices into it. The little wall modules recieves the signal coming along the electrical lines and turns the device on/off/dim, etc. The reason I like the Firecracker is that it is a "dumb" device. All program code must exist on the PC therefore I have more control. They have other devices which you download program code to then they are autonomous which I don't think is what you are looking for. I use a) & d) extensively here. If anyone wants the code or more info, just ask.
