I've got an application running under Borland C++ 3.0 on a Dell 386 box (MS-DOS 5.0), using the BGI graphics library to manage the VGA display. I'm trying to use Borland's "ctrlbrk" function to handle ^C/^Break events (setting a flag that another routine eventually notices), and it seems to work as advertised, except that I can't seem to suppress the echo of "^C<CR>" to the screen (which trashes the display). Obviously there's some chunk of code outside the default ^C handler which is doing this echoing (the BIOS keystroke handler, maybe?), but I thought I'd check before trying to hunt it down myself. Any suggestions?
