Request for Comments: 562 BBN-TENEX
NIC: 18638 28 August 1973
Updates: RFC 495
References: RFCs 513, 529
Modifications to the TELNET Specification
Almost four months have passed since the new TELNET Protocol
specification was published. Since then, only two RFCs have been
issued suggesting modifications, and the most recent of these was
distributed two months ago. Further, the date from the old TELNET to
the new TELNET (1 January 1974) is only four months away. It
therefore seems appropriate to officially modify the specification to
account for the suggested modifications, and to declare a moratorium
on the incorporation of additional suggestions until after the
switchover. (Of course, no moratorium on the specification of
additional options is required.)
The two attached documents represent the revised TELNET Protocol
specifications; they replace NIC #15372, TELNET Protocol
Specification, and NIC #15373, TELNET Option Specifications. The
remainder of this RFC summarizes the changes. Page numbers refer to
the earlier documents.
