Need help about controlling the serial/parallel port!!!

[Aigneryu]

I have to program my computer to output signals to control my chip which is already mounted on a PCB.

First problem is that the signal level is not proper for direct input to my chip. And the second problem is that I don't know how to control these ports. In fact, I need a serial control bit stream aligned with a clock for shift registers.

Do anybody know where can I find some useful material for programming?? An example or reference books.
