Can you be a little more specific ? Does a program listen to a wake-up signal, or what ?

No I need to send a wake on lan command using delphi to a "sleeping" computer. There is a whitepaper at Microsoft (http://www.microsoft.com/hwdev/specs/PMref/PMnetwork.htm) on the data portion of the packet structure. What I need to know is how to broadcast this packet across the network, thereby (hopefully) waking the computer.

Are u sure that a program on a sleeping computer (isn't the program "sleeping" too ?) can wake it up ?

I thought it's a hardware-function ..

Due to the problems and some incompatability issues with some network cards the WOL functionality has been dropped from our application.

Seems to me like if the program can receive data from the network, and you let the program for example write a little file to the harddisk, after it receives its 'wake-up call', the computer might become active again. The file written to disk (just to activate the diskdrive and thereby the whole system) can be deleted after the wake up. Or it can receive and record some usefull data, whatever you want. There are various ways to send data over the network, depending on the delphi used (Client/server) or the components used (Mailslot or other).
