    I just tried the following program under Turbo C++ 1.00

main()
{
    int c;

    while((c = getch()) != 'q')
    {
        printf("%c\n",c);
    }
}
I compiled using tcc -A tst.c (-A is for ansi mode I believe)

It doesn't seem to have the same behavior that the original poster was 
upset about.  getch handles the ^c without any problem.  In fact, it
loves it when I type a ^c.  (a very subtle bit of humor.  Run the program) :-)

Turbo C++ also has the getcbrk and setcbrk functions that might be of use.

Is there a possiblity that it has something to do with the version of DOS?
(I'm running Zenith 3.3+)
