I believe that Win32 console applications executed via Odin are actually run in a PM window rather than a real OS/2 console window and ANSI codes are probably not interpreted there.

I don't think that you can ever get cursor keys from stdin under OS/2 - only regular characters are delivered that way. You'd need to use the (16-bit) kbdcalls with thunking, or some wrapper around it (EMXWRAP.DLL from EMX runtime, or something else).
