You can use screen to connect to a serial console in Ubuntu
I have to work from home with it being pretty apocalyptic out there due to the covid 13 virus. At work I use a windows machine and use Putty. Here at home I use Ubuntu and need a serial terminal to communicate with the hardware I’m working with.
Turns out I can use screen, awesome!
sudo apt-get install screen -y
screen /dev/<your device here> <your baud rate>
Press ctrl-a type the following
Then hit enter
Stay safe out there!
