I mean, the PinePhone has a switch to change the audio jack from audio into some kind of data transfer protocol. I guess someone could make it work.
Audio jacks have been muxed as debug serial for ages.
I use 3.5 stereo as an rs232 connector all the time. A poe ethernet to serial would be a huge help to me.
I think you would need another connection (ie. a 3rd stripe, TRRS vs TRS cable) for data transfer. Although digital audio is all data anyways I guess and now I don't even feel right but I've already typed it out.
