With that said, if you are interested in learning more about the inner workings, Lior Elazary has made the most progress that I'm aware of:

I'm interested in seeing if real time (or near real time) software
control of a UV-5r is practical. Basically, I'd like to setup a
Raspberry Pi, some additional hardware [custom shield] and an Ethernet
connection [w/ PoE?] that could plug-n-play with a UV-5r that to provide
a remote [tower top?] back end to a soft [chirp based?] front end on my
Linux desktop or android smart phone.

You can't remote control the UV-5R from the serial port. You can only clone (download and upload) the memory channels and settings.
