Network Working Group ISO Request for Comments: 905 April 1984 ISO Transport Protocol Specification ISO DP 8073 Status of this Memo: This document is distributed as an RFC for information only. It does not specify a standard for the ARPA-Internet. Notes: 1) RFC 892 is an older version of the ISO Transport Protocol Specification. Therefore this RFC should be assumed to supercede RFC 892. 2) This document has been prepared by retyping the text of ISO/TC97/SC16/N1576 and then applying proposed editorial corrections contained in ISO/TC97/SC16/N1695. These two documents, taken together, are undergoing voting within ISO as a Draft International Standard (DIS). 3) Although this RFC has been reviewed after typing, and is believed to be substantially correct, it is possible that typographic errors not present in the ISO documents have been overlooked.
