Audio Port: Data Transfer over Audio Port
https://mobileembeddedsystems.blogspot.com/2010/03/data-transfer-over-audio-port.html
Audio output port is primarily used to output sound signals. Usually the signals are bipolar. Inside the electronic devices, the audio output is usually generated by a DAC (Digital to Analog converter) in combination with audio amplifier and filters. The output could be mono or stereo. Audio input port is usually in the form of mic (microphone).

So, let’s see if can send a serial signal out the audio port. Serial Communication Here’s a refresher on the asynchronous serial protocol. It runs at a pre-specified baud rate (commonly 9600, 57600, or 115200), which determines how wide each pulse is. Data is sent in “frames”, which include A start bit (low logic level) 5-9 data bits
