Assuming that the above means you're focused squarely on "computer = PC" then
there are essentially three approaches: (1) get hold of a 12 to 15 year old PC
running MS-DOS or other non-protected OS, or (2) invest in LabView or similar
software for a modern PC, or (3) for a modern PC use some existing library (C
or C++ library, language-independent ActiveX control, whatever).
Perhaps e.g. LabView is coded in C++, but I'm fairly sure it's beyond your
current abilities to do that sort of thing in C++ in modern Windows or Linux:
you need to choose one of the three approaches outlined above, or perhaps
something I haven't thought of.
