addressing hardware ports using c++
I am using Borland c++ 5.02 for fetching data using an A/D/A convertor card PCL-208. I was using function inport and outport for transferring data. When I was using these functions with borland c++ 3.1 version (after including dos.h file) my program was running fine. Now I am suppossed to use these finctions with Borland c++ 5.02 version. Though the help file gives these functions but using these functions gives an error. The error says "call to undefined function outportb & call to undefined function inportb.
I am not able to find a solution.
Help me if you can
