It all sounds very complicated to me.

If I wanted to construct a modem.rules file what number would I use in the
file name and why?

What would be the syntax of the file, and what would the various options do?
I guess if you've designed the thing or played with it often enough, it all
looks simple and straight forward but approaching it for the first time, it
all seems rather intimidating (for me at least, or maybe I just haven't woken
up as yet).
