	unsigned status;

	status = _bios_keybrd( _KEYBRD_READY );
	if( status == 0 )
	  /* no key pressed */
	else
	  /* some key was pressed */


	If you are concerned about the SHIFT, CTRL, ALT, SCROLL LOCK,
	NUM LOCK, CAPS LOCK, and INSERT use _bios_keybrd( _KEYBRD_SHIFTSTATUS )
	with the above.

	-------- OR ---------------

	You can use the function int kbhit(void) to check if a key has been
	pressed but not the SHIFT, CTRL, ALT, ....
