Constants

CHAR_ENC

Code character encoding for each mode.

public const CHAR_ENC = [
    // MODE_UPPER (initial mode)
    0 => [
        32 => 1,
        // ' ' (SP)
        65 => 2,
        // 'A'
        66 => 3,

CHAR_MODES

Map character ASCII codes to their non-binary mode.

Exceptions are:

  • the space ’ ’ character (32) that maps for modes 0,1,2.
  • the carriage return ‘\r’ character (13) that maps for modes 3,4.
  • the comma ‘,’ and dot ‘.’ characters (44,46) that map for modes 2,4.
public const CHAR_MODES = [
    1 => 3,
    // '^A' (SOH)
    2 => 3,
    // '^B' (STX)
    3 => 3,
    // '^C' (ETX)
    4 => 3,
    // '^D' (EOT)
    5 => 3,
    // '^E' (ENQ)
    6 => 3,
