 * C = 0x20
 * D = 0x00
 *
 * There are two sets of arrays: one to test that the setting is correct,
 * the other to test that the getting is correct.
 * Note that the 'get' values must be constants in processor-endianness,
 * as libmodbus will convert all words to processor-endianness as they come in.
