Doxygen is useful to document each function, but relies on the developer to add it. I don't think doxygen can present pretty graphs of C code base and runtime flow. I am sure there must be some tools that work with CLANG/LLVM to do what you want. The runtime flow is probably called the "control flow graph" or CFG. Also, tools that manipulate, graph the "Abstract Syntax Tree" or AST might also help. So, google for those terms and you should find something.

It has good support for serial ports, not used the parallel support, but it should be ok.

If you choose to use DOSBOX, http://www.dosbox.com I have some patches that make it work better with data logging applications. My patches make the timestamps use the linux system clock, instead of DOS "ticks" which can be out by about 10 minutes each day. If you instead choose to re-write the application, you might wish to consider displaying the output in a web browser, ie. write a web app, or provide the output via the REST web services protocol.
