Hardware Access Console is a free program to run from the Windows command line (or from MSDOS environment). Its main function is practically the same as the famous debug.exe file in the old days of the MSDOS, which was responsible for debugging, scrutinizing and eliminating errors in the files to which you applied it.
Well, this Hardware Access Console will allow you the same, but from Windows. With it you can access some hardware devices, check them, try to debug some anomalies, read / write in memory, access the input / output ports, and so on.
