HEADPHONE. Read & Send Data

I have seen several posts in the comunity that handle some issues concerning the detection of the Headphone status and sending data to its port.

Has anyone come across or have a library or solution of how to read data from the headphone (audio jack) port?

I currently managed to develope a B4A app that can auto detect headphone plugged status with a service and several activities to coupe with all UI funcionality. The only thing missing is to be able to read and send data to headphone port....
