//
// Lev - is the Level code
//
// 00 - Success

// 11 - Error
//
// C - is the Customer code flag (must actually be set)
//
// R - is a reserved bit (unused)

//
// Code - is the facility's status code
//

// for a better error code recognition by the reader

// have to be adjusted for a platform other than Windows
