Linux Serial Console

To configure Debian 11 for a serial console


Edit /etc/default/grub to add the console setting to the end of

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=d6a8791e-201a-4207-99e1-eafadec6713f console=ttyS0,19200n8"

Then update grub to use the new setting.

sudo update-grub

Once the systemd changes are made it's worth rebooting to see that the boot process appears on the console.


sudo systemctl enable serial-getty@ttyS0.service
sudo systemctl start serial-getty@ttyS0.service
