well here's a very simple example which works - a simple example that
doesn't would help focus:

#include <curses.h>

int main()
{
        int ch;

        initscr();
        raw();
        noecho();

        while ((ch = getch()) != EOF) {
                if (ch == '!') {
                        endwin();
                        system("sh -i");
                        refresh();
                } else if (ch == '\033') {
                        break;
                } else
                        addch(ch);
        }
        endwin();
        return 0;
}
