I was hoping I could use scp to copy files from my computer to the Brick but it turns out that scp is based on ssh. So that’s one difference between telnet and ssh.
Also, I was cocky and killed and restarted the lms2012 process on my Brick via telnet and now the Brick won’t shutdown. When I started lms2012 again it was like my prompt was waiting for the new process. When I tried to shut down the Brick via LMS2012 on the Brick I got a few error messages in the telnet prompt and a message about something being saved, and then nothing happened. It seemed like the Brick got stuck somewhere. I had to press the back and the middle button to reboot the Brick.
Anyhow, Brick is up in wifi and I can connect to it through Telnet. Happy and excited!
