Links don't work as their system with open.dll is... well... pre-dynamic languages. Long time ago there was just static HTML and no way to display dynamic stuff. So people used Shell Scripts written in say C to generate dynamic HTML text output. This is like technology that is over 30 years old. This was obsolete more than 25 years ago as dynamic web languages such as PHP became popular.
After few decades you would thing they would upgrade
Maybe they are going for the same stuff as airport traffic control which is 50+ years old.
