You could call it from a systemd or init.d script. The only concern would be exiting in case you want to access the command prompt or some other utility (vim, mutt, w3m etc. ) Likely I would add a mode where it operates off stdio redirected to the port instead of the serial port device directly. Then a simple Ctrl c would cause Laddiealpha to exit. > (So that only a power cable and M100 Serial cable are needed to use it as > a TPDD) > Can Laddie alpha be configure to write to the USB thumb drive? > It will write to whatever directory you are in. If you only want to write to a usb drive pnly a udev/hot plug script could launch Laddiealpha automatically once the usb is plugged in and the filesystem mounted. But really you don't need "headless" operation since we have a screen on the model 100 and Telcom. I would just set up Getty on the serial port from which I could launch Laddiealpha manually to run from any directory. > > I found this routine: > ADDING A SHUTDOWN BUTTON TO THE RASPBERRY PI > I've see some simple designs to add a battery or super cap to the pi board that gives time to shutdown gracefully. We're adding such a thing to our pi units at work since the sd flash corrupts frequently due to non graceful shutdown. -- John.
