>From src/devices/grotty/tty.cc:

  #ifndef IS_EBCDIC_HOST
  #define CSI "\033["
  #else
  #define CSI "\047["
  #endif

  // SGR handling (ISO 6429)
  #define SGR_BOLD CSI "1m"  
  #define SGR_NO_BOLD CSI "22m"
  #define SGR_ITALIC CSI "3m"
  #define SGR_NO_ITALIC CSI "23m"
  #define SGR_UNDERLINE CSI "4m"
  #define SGR_NO_UNDERLINE CSI "24m"
  #define SGR_DEFAULT_COLOR CSI "39m"
  #define SGR_BACK_DEFAULT_COLOR CSI "49m"

and this:

  void tty_printer::put_color(unsigned char color_index, int back)
  {
    if (color_index == DEFAULT_COLOR_IDX)
      color_index = 9;
    putstring(CSI);
    if (back)
      putchar('4');
    else
      putchar('3');
    putchar(color_index + '0');
    putchar('m');
  }

color_index is in the range 0..7.
