Hi all, Sorry if its a FAQ but i don't find any answer for this topic. i need to test (NOWAIT), the presence of keypressed/depressed on a terminal and then read the scan code, like for a piano pc keyboard. my questions are as follows: 1. is it a general C function which may scan a terminal without waiting? 2. how to get the scancodes? of course i can poll tje (0x64) keyboard port on a i386 architecture, but this is not a general method, and it is suited for a distant terminal for instance. Any hint would be appreciated. thanks in advance. rmgls
