I am using a keyspan model USA-19HS USB-Serial adapter and a null serial calbe to connect a Ubuntu 16.04 LTS computer to Raspberry Pi 3 running Ubuntu Mate 16.04. I wish to control the Pi as a headless system using the Ubuntu 16.04 LTS computer. I have tried many different ways of getting this to work but have been unsuccessful. For example one way I tried was:
On the Pi
- install a fresh version of Ubuntu Mate 16.04
- sudo apt-get update
- systemctl enable [email protected]
- systemctl start [email protected]
- systemctl is-active [email protected]
The last command shows that it is indeed active. When I use minicom or screen on my Ubuntu computer to try in login I get partial messages from the login like “pi logi” and “Ubunt” and it makes it to where I am unable to login in to the Pi using serial port. Any help would be greatly appreciated. Thank you!
