Empty sub parameters - * are set to -1 (no ZDM for sub parameters). - * - * About prefix and intermediate bytes: - * This parser follows the assumptions of the vt100.net parser with these restrictions: - * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f - * - max. two intermediates are respected, byte range 0x20 .. 0x2f - * Note that this is not in line with ECMA-48 which does not limit either of those. - * Furthermore ECMA-48 allows the prefix byte range at any param byte position.
