Hereby the situation: I'm working on a Android Tablet that must work in Accessory mode. Reason why is because the tablet can't provide enough power to perform the communication with a Serial USB microcontroller and remain charging it's battery.
In order to achieve a successful communication, I must be able to set a few serial conditions for Modbus/RTU
- Serial Port Address (i.e. COM1, COM2...)
- Baud Rate (19200 bps)
- Data Bits (8)
- Stop Bits (1)
- Parity (None)
An excellent example in Delphi would be Modlink.
A good guidance would be UART https://github.com/ytai/ioio/wiki/UART
Meanwhile, I've found some useful projects but they were intended to work on Host mode.

I'm looking for any valuable information, guidance and references on how should I proceed to create an Android Application that can communicate with Serial USB.
How can I achieve this?
Note: I'm using Android Studio.
