// Here is the table of global arrays which represent each type of command
// supported in the IntelliPort standard loadware. See also i2cmd.h
// for a more complete explanation of what is going on.
//------------------------------------------------------------------------------
// Here are the various globals: note that the names are not used except through
// the macros defined in i2cmd.h. Also note that although they are character
// arrays here (for extendability) they are cast to structure pointers in the
// i2cmd.h macros. See i2cmd.h for flags definitions.
