I'm trying to make a program that when you push a button, it sends a signal through the serial port (or com/paralell.. whatever), but I'm not sure how to do this.  Any and all help would be GREATLY appreciated..

You can use the MSCOMM32.OCX (Microsoft Comm Control) included with VB to send and receive data using the serial port (COM port). It is very simple and there is an example on how to use it in the VB help for the control.

You can find very useful information on using the parallel port in the following URL's:

Hope that helps.
