DOS_BOX have problem in the bad emulation of external parralel port, which I need to use,why? This is basic request = connection with external peripherials!!! Have you any information for resolve this problem?

I have bad experience with your product DOS_BOX. I have old programmer for ST6 microcontrolers which require the original DOS for good function. In window´s DOS it doesn´t work. I mean that problem is in the bad emulation of external parralel port, which my programmer use.
Why DOS_BOX doesn´t emulate the standart peripherials (LPT, COM ports)? This is basic request = connection with external peripherials!!!

Speak your mind, please, about this problem, because my work with this programmer is very dificult throw booting to DOS and rebooting to windows.
Thank you for information.
