  ------------------------------- Zitat Anfang ------------------------------- 2.7. 7bit Data "7bit data" refers to data that is all represented as relatively short lines with 998 octets or less between CRLF line separation sequences [RFC-821]. No octets with decimal values greater than 127 are allowed and neither are NULs (octets with decimal value 0). CR (decimal value 13) and LF (decimal value 10) octets only occur as part of CRLF line separation sequences. 2.8. 8bit Data "8bit data" refers to data that is all represented as relatively short lines with 998 octets or less between CRLF line separation sequences [RFC-821]), but octets with decimal values greater than 127 may be used. As with "7bit data" CR and LF octets only occur as part of CRLF line separation sequences and no NULs are allowed. 2.9. Binary Data "Binary data" refers to data where any sequence of octets whatsoever is allowed. ------------------------------- Zitat Ende ---------------------------------
