Re: Getting a serial console to work on Jessie

Hello, Thanks for all the clarification. I now find myself in need of doing this again on another server running Jessie, and I just want to make sure I'm clear on what the best procedure is. As I understand it, I should copy /lib/systemd/system/serial-getty@.service to

Thanks. I actually found that site in a Google search, and it's where I found the tip on copying the /lib/systemd/system/serial-getty@.service template file to customize the baud rate, etc. Specifically, I found the info I needed at: http://users.wowway.com/~zlinuxman/serial.htm#Systemd
