ReadyNAS Ultra 6 - Replace OS with any linux distro or NAS-OS e.g. Openmediavault possible?

Ok I found out how this mini-LCD work. Source, see copy below: https://web.archive.org/web/20141229214439/http://www.nexentastor.org/boards/9/topics/8238 LCD info The LCD module on the ReadyNAS (Ultra/Pro series) shows up in Illumos/Solaris as a serial port device. On my systems, it is always described as /dev/term/b Here are the commands currently available for font/bitmaps development to be sent to the serial port: Value Outcome C X Y ­ Set x, y coordinates (0 <= x <= 127, 0 <= y <= 33). Hex only, example c40 10, set x=64 y=16. E Clear screen F N ­Set font size. N=(0:Ariel 9, 1:Ariel 18, 2:Mono58) L string ­ Display the string, starting from (x, y) B h w b Set height,width,bitmap, starting from (x. y) i0-3 Scroll (0:None, 1:Right, 2:Up, 3:Diagonal) In practice, a runner could be created to show faulty disks and such to the LCD screen. For now, all I have it do is show 'NexentaStor' on bootup. $ cat /etc/init.d/lcd #!/bin/bash echo "E" > /dev/term/b sleep 0.5 echo "L NexentaStor" > /dev/term/b On Debian it is a little bit different: Check out what serial devices are connected: sudo dmesg | grep tty Add your user to the needed groups: sudo usermod -a -G tty dialout username Log out, log in again and then test both serial devices: echo "E" > /dev/ttySx to clear the screen, then echo "L Text" > /dev/ttySx
