Field Detail

START_BAR

static byte[] START_BAR

The Start bar

STOP_BAR

static byte[] STOP_BAR

The Stop bar

ESCAPE_BARS

static byte[][] ESCAPE_BARS

Bars to represent escape chars index 0 = First escape char used in ASCII_CHARS array index 1 = Second escape char used in ASCII_CHARS array index 2 = Thirth escape char used in ASCII_CHARS array index 3 = Fourth escape char used in ASCII_CHARS array

BARS

static byte[][] BARS
