No, no, no, a thousand times no, don't use DOSbox. DOSbox is for games and games alone. Don't believe me? The developers say it themselves:
DOSBox IS NOT SUITED TO RUN YOUR NON-GAMING DOS APPLICATION. "Search the forum, there are lengthy threads why a games-targeting emulator is not what you need. It can go wrong at any random time for any nondeterministic reason. Don't, just don't."
