I have a routine in Turbo-C. It detects user's keystroke with bioskey().
I want to detect Ctrl-C but ignore Ctrl-Break.

getkey()
{
	while (!bioskey(1))
		;
	return (getch());
}

It works fine for Ctrl-C. However, if I press Ctrl-Break, the program hangs.

When I change 
			while (!bioskey(1))
to
			while (!kbhit())

then both Ctrl-C & Ctrl-Break show ^C on screen and terminate the program.

When I use ctrlbrk() to set a new control-break handler, pressing Ctrl-C
or Ctrl-Break won't terminate the program but leave ^C on the screen.
Moreover, I cannot detect Ctrl-C this way (using kbhit())

Using bioskey() + ctrlbrk(), I can detect Ctrl-C, but again Ctrl-Break hang
the program.

Somehow bioskey() doesn't work with Ctrl-Break. 
Does anyone have any solution?
