I'm looking at these schematics and it includes an Atmel at90s2313... I'm assuming this is going to need to be programmed with something? Are there any other solutions other than this?

I presume you'd need to code the pic to convert RS232 signals to power up/down commands to drive the power relay.

I was thinking more about this last night, and if you are just wanting a way to turn power on and off via com port, you don't actually need anything more than a couple of diodes and a relay.

I guess the trick would be getting it to work with the program then.

Is it your own program or someone else's? It's much simpler if the code is yours, obviously! ;-)

Yep. Unfortunately it is not mine. It is a commercial program that sells a power controller board but also includes the schematic. I was trying to see how feasible it would be to just make my own.

You'd have to reverse engineer their com protocol too in that case. Do you have a logic analyser?

at90s2313 this one need to be programed as well

Do you ask the owner of HDDUP. maybe he can give you the source code for this
