We have ported
sff to InkBox OS as
InkBox Terminal. It is a Qt-native app using libvterm to interact with a virtual tty.
The default bundle includes an ssh client, thus, provided your device is rooted, you could ssh to the root filesystem. If not, you could still interact with another host on your network or on the Internet.
