You can look at one of the simpler backends, like the cressi leonardo. 
But the first step will be to figure out how the protocol works, and how 
to interpret the data. Since it seems to be ascii based, you won't need 
much coding there.

The manual is for using the libdivecomputer api, not implementing a new 
backend.

Maybe you only captured part of the download? I suggest you keep 
capturing with portmon for as long as the sentinel application is 
running.
