send command through serial port

Specs: Windows Vista
Good day,

I am trying to shutdown any computer using an external device that is connected either through the serial port or the usb port. Basically its a device with a pic30f4013 microcontroller which is programed using C language. So what I want is to shut down the computer with some signal that I can send through the rs232 from this microcontroller. Does anyone knows how to solve this problem. Thank you...

I can't help you with that but you do understand just shutting down the hardware will corrupt the disk and OS?

This is why programs like APC UPS have softare running on the host that listens to the rs-232 port and then gracefully shuts the OS down as well as the hardware.
