*   PACKAGE:     Linux tty Device Driver for IntelliPort family of multiport
*                serial I/O controllers.
*
*   DESCRIPTION: Definition table for In-line and Bypass commands. Applicable
*                only when the standard loadware is active. (This is included
*                source code, not a separate compilation module.)

// 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.
