Edition
RFC Editor plain-text edition, put into machine readable form by Robbie Bennet in 1999, complete. The heading block and the note of that edition (whose square brackets are left out) are in the header and the footer; page headers and footers are left out; the code table and the tables of the legend are reproduced unchanged, without the blank lines between the rows of the table of control characters; the footnotes of section 4.2 are set as paragraphs; the misreadings of the original (“X’OD’”, “(252)”, “FS File Separator IS)”) are kept.
Rights
All RFCs may be freely reproduced and translated (unmodified).
