I had seen the original suggestion to use CTTY to redirect the console to a serial port but
I had seen the original question on how to redirect DOS to use the serial port and I probably should have chipped in then, but now you know the limitations of CTTY. CTTY to a serial port only works for programs that use the DOS system calls to generate output and read from the keyboard. It doesn't work for anything that uses BIOS calls or directly manipulates video memory. It might be able to handle Ctrl-C correctly but it definitely can't handle Ctrl-Break. In short, it is very limited. Programs that use ANSI escape codes to paint and manipulate the screen will work in theory, but there are very few of these. Some of the early versions of the Norton Utilities can use ANSI instead of direct screen writes, but this technique did not catch on because it is very slow compared to "normal" BIOS calls or direct manipulation of the screen.
