Hi... I have a door on my house which I want to monitor.  Whenever the door opens or closes, I want my always-on PC to write the timestamp to a textfile.

What hardware do I need?  I'm a reasonable software programmer, so I can read serialports and whatnot.

Any help would be appreciated!

Unless you really want to get "down and dirty" with a serial port and serious coding, I would suggest the CM15A USB computer interface which comes with Active Home Pro (AHP) software.

The AHP software has a built in event log ("Activity Monitor").

You can also write your own software easily using the AHP SDK.

It is often advantageous... to look at what the technology has to offer.. before deciding what to do. I would also use the AHP (and CM15A) as Bill. But I would consider email notification (and maybe include pics).

Doing what you want is a very simple task. Unless your using a security sensor to monitor the door!
If your using a security sensor you'll need the AHP all plug-ins kit(includes OnAlert for monitoring security sensors)
If you monitor it with a non Security motion sensor  and you have the CM19A you can download the AHP SDK which will allow you to write a logging program.
If you have the old CM11A and plan on using a non security sensor you can still write something your self but it is a little more difficult.
you'll need to download the X10 protocol
