I've installed a control-C handler (INT 23) for an application I am
writing. It works but either DOS or BIOS still echoes the "^C" to
the console.  This is a problem since it's a graphics application and
I want to avoid a screen redraw whenever the user hits ^C (BTW, my
handler does nothing but IRET).  I'd also like to avoid such extremes
as redirecting stdout or hooking the keyboard interrupt handler. Also
the keyboard-intercept interrupt is not supported on all PC's.
Any ideas would be much appreciated.

Thanks,
