Android Question How communicate PC and Mobile with Serial?

[darabon]

I need to communicate between device and pc
Like this, I have software in windows and send data to mobile with serial port
My project is connecting the device to pc and send a request(take a picture) to mobile with serial port and in-app, take a picture and save it
Maybe?
Tip: I don't want to use Socket or WebSocket

Serial port requires a supported USB to serialport converter. You can then use felUsbSerial or UsbSerial2 on the Android and jSerial on the PC.

Why do you not want to use socket? It will do the job quite easily and can do it over wifi not to mention the data transfer is much faster than a serial connection.
