I actually moved that old page over the the above page, and updated them in the process. Much of the info on the old page is outdated. The new commands are on this page:
https://github.com/synthetos/TinyG/wiki/TinyG-Configuration
The setup info on the bottom of the old config page is in the Tuning page:
https://github.com/synthetos/TinyG/wiki/TinyG-Tuning
Are there other answers the old wiki has that are not in the new wiki?
