Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

37// Here is the table of global arrays which represent each type of command
38// supported in the IntelliPort standard loadware. See also i2cmd.h
39// for a more complete explanation of what is going on.

42// Here are the various globals: note that the names are not used except through
43// the macros defined in i2cmd.h. Also note that although they are character
44// arrays here (for extendability) they are cast to structure pointers in the
45// i2cmd.h macros. See i2cmd.h for flags definitions.
