how do u make c++ communicate with the hardware?

[Bmxpunk86pl]

would somone give me an example of a C++ program that communicates with harddrware directly. how would i make c++ to detect what kind of modem a comp is running.

[Bmxpunk86pl]

like say i wanted c++ to scan the com ports or something.

[Bmxpunk86pl]

say like the statement "detect_modem:"

I know that modems usually comunicate with each other thru AT- commands. I also know that the procedure that we all know in Windows- ask modem state- is actually a one AT command, than modem returns useless garbage and windows puts this on the screen. Only when modems are connected, can we use them as COM ports and forget that they are modems.
