That depends on what language you are using, if your Using C, or C++ Even, in
Windows you can usualy include conio.h which has a getch(), myself i've always
used the DevC++, and sorta riped out their conio.h and included it in my own
project for windows development.   In linux you can use Read() Write() with
stdio, it works great.. test with Select(), then if there is data, use Read()
to get it, sorta like sockets, but works perfect for console i/o.
