Re: Serial Console

Before plugging the device in, enter lsusb in the terminal. Plug it in, and enter lsusb again. Check for differences. If it's a cheap USB serial device, it's likely to display as a QinHeng Electronics HL-340 USB-Serial adapter or similar. It won't need drivers. Check the end of the output of the dme...

Re: Autostart GUI and read serial data

Is the serial GPS connected via USB? If you have other USB devices plugged in, maybe the serial GPS is coming up under a different device name under certain circumstances on the Raspberry Pi 4.

Re: Linux pipe command to copy

Yeah, whatever MP4Box does, that is massively unlikely to work the way you'd want it to. If MP4Box only prints the file name to standard output and nothing else , you could use: MP4Box -add t.h264 t.mp4 | xargs -I '{}' cp '{}' ../share This will fail if there's a space in the file name.

Re: Raspberry Pi ** Sold over 25million units **

Maximum C64 sales are 17M although that's debatable, could be as low as 11. We may actually have sold more Pi3 than even the high number. That's great news! Sadly, these facts won't help my Commodore-partisan friends. "It's not a home computer because it's not" seems to be the best argument. It's u...

All the devices you list — well, the hub and the USB→SATA adapter — are USB 2. This negates any advantage of using a Raspberry Pi 4. I know you said you didn't care about speed, but your once or twice per week backup might still be backing up the next time you want to do it.
