If you are using Win16 programming, you can do this simply using the inport () and outport () functions to read and write to/from the com port.  If you are using Win32 programming, you must use a device driver.  One that I'm currently using that is quite adaptable (and you won't have to write it yourself) is a shareware device driver from:
http://www.entechtaiwan.com/tools.htm.  It's TVicHW32.dll. It's a dll that you can incorporate with your hardware data acquisition program to directly access the com ports.

Other than using a device driver in win32, you can't directly access the hardware.

If you aren't using windows or dos, this answer may not work.
