I've been having fun with the command-line Wolfram Language interpreter across a serial terminal (The graphical one is WAY too slow on my 1st gen. Pi). I have a couple of queries:
1) How do I save a session to a file, or write a program so I can run it later?
2) I can't get it to connect to the internet. If I try something like ChemicalData["Silicon"] I get an error. The error says "Use Help -> Internet Connectivity", but how on Earth do I get to this function?? All the help files point me at the "Internet Connection Dialog", but there's no such thing on the command line. How do I access the preferences to allow Wolfram to access the internet?
