[Interest] QtSerialBus on Android

[Denis Shienkov]

Hi,

> Yes I saw that, but same apply to QtSerialPort, i don't see why it's
not available on Android. Android IS a Linux system, and it does have
the tty bits.

Because it requires the root right to use the serial ports in Android.
Do you have a root rights for any device? Do you have the USB/Serial
drivers for any device in a device kernel? :)

You can build QSerialPort on Android manually and use it if you want.

BR,
Denis
