are you using a PC or an embedded system? If a Windows PC you can only access hardware from DOS, Win95 or Win98 - more modern versions of Windows such as 2000, XP, etc will not allow user program to access hardware directly. For eaxmple, when we need to talk to hradware directly we often dual boot Windows XP and DOS. Which compiler were you thinking of using?
have a look at

Thank you sir for the response.
I have to develop a lift operator using 8085 microprocessor.
I plan to connect the hardware to pc through a parallel port,
then later may be I'll like to implement it on an embedded system.
I am using Turbo C 3.0 for this.
I am new to External hardware interaction and microcontroller
programming. So plz help me with some e-books or tutorials on this topic.
Thanks once again for ur help.
