STATUS current
DESCRIPTION "Represents textual information taken from the NVT SCII character set, as defined in pages 4, 10-11 of RFC 854. To summarize RFC 854, the NVT ASCII repertoire specifies: - the use of character codes 0-127 (decimal) - the graphics characters (32-126) are interpreted as US ASCII - NUL, LF, CR,BEL, BS, HT, VT and FF have the special meanings specified in RFC 854 - the other 25 codes have no standard interpretation - the sequence 'CR LF' means newline - the sequence 'CR NUL' means carriage-return - an 'LF' not preceded by a 'CR' means moving to the same column on the next line. - the sequence 'CR x' for any x other than LF or NUL is illegal. (Note that this also means that a string may end with either 'CR LF' or 'CR NUL', but notwith CR.) Any object defined using this syntax may not exceed 255 characters in length."
SYNTAX OCTET STRING (SIZE (0..255))
v1 TC 由物件名稱後面接著 ::= 項目組成，然後附加有效的 SYNTAX 定義。 例如：
DisplayString ::= OCTET STRING
