I am trying to connect a serial (dumb) terminal to my ubuntu 16.04LTS system. There are some how-to's around, but I have problems with them . What I need is a "simple" logon message on the serial terminal - after all UNIXoids are multi-user-systems. One of the suggestions even led to a dead system, requiring a re-install.
GtkTerm using /dev/ttyS0 connects OK to the terminal, i.e. typing text on the serial terminal and reading it on GtkTerm works OK as well typing on the Gtk and reading on the dumb terminal - so the connection is set-up basically OK.
I read "https://help.ubuntu.com/community/SerialConsoleHowto", but I am not sure which portions I need when I need an additional "login" screen on the dumb terminal, "only".
For the above text, I set-up the file for ttyS0 as mentioned but I am facing issues when entering
sudo start ttyS0:
start: Connection to upstart not possible: Failed to connect to socket /com/ubuntu/upstart: connection set-up rejected."

I don't want to tamper with GRUB etc, I just need an Ubuntu login-screen, like the ones you see when typing e.g. CTRL-ALT 1..6, only on the serial dumb terminal.
Any advice pointing me in the right direction will be highly appreciated
/sbin/getty -L 115200 ttyS0 vt102in a terminal, things work as expected? If so, then the issue is only how to execute this same statement on startup of the computer. The instructions you link to (where I suppose you have followed the two steps for "Karmic and newer"), are somewhat outdated. Upstart has been superseded by
