What is the difference between downnow and downfromserver?
The downfromserver command will start the download function and the D8 will get the update.d8 file via the download path that has been set in the setup menu. This will only work when the path has been set and the mode is either OFF or set to Schedule.
When downnow is used, files are downloaded according to the down.lst list. The download path is irrelevant, as it will only look for the down.lst list on the local drive.
