NWG/RFC# 580 JBP 25-OCT-73 06:00 19849 note to protocol designers and implementers Hereafter proposed protocols shall be submitted in the form of on-line documents, preferably as nls files at the Network Information Center. This will greatly facilitate the review process and enable editorial and substantive changes to proceed quickly. This also will permit timely updating of protocol documents as may be neccessitated by future decisions. On-line documents are also easily distributed to the network community. If you find great difficulty in complying with this request please contact me. It should be noted by all Telnet protocol readers and especially implementers that all the existing Telnet Options that involve subnegotiation are modified [see RFC 562] to terminate the subnegotiation strings with IAC SE. The value of SE is 240. Also note that within subnegotiations the occurance of a byte with the value 255 [IAC] requires doubling that byte on transmission. Please note that my address has changed to: Jon Postel The MITRE Corporation Mail Stop W185 Westgate Research Park McLean, Virginia 22101 Phone: (703) 893-3500 x2350 On-line messages will reach me addressed to either POSTEL@ISI or JBP in the NIC Journal.

§1Submit Proposed Protocols Online
Jon Postel asks that proposed protocols be submitted as online documents, preferably as NLS files at the Network Information Center. He says online documents make review easier, allow editorial and substantive changes to proceed quickly, support timely updates, and are easy to distribute to the network community.
He asks anyone who has great difficulty complying to contact him.
Protocol proposals should be shared as online files. This makes them easier to review, change, update and distribute.
§2Telnet Subnegotiation Ending
The note says all existing Telnet options that use subnegotiation are modified as described in RFC 562. A subnegotiation string ends with IAC SE, where the value of SE is 240.
If a subnegotiation contains a byte with value 255 (IAC), the sender must transmit that byte twice.
A Telnet subnegotiation ends with the two-byte marker IAC SE. If the data itself contains IAC, send that byte twice.
§3Updated Contact Information
The note gives Jon Postel's new mailing address at The MITRE Corporation in McLean, Virginia. Online messages can be addressed to POSTEL@ISI or to JBP in the NIC Journal.
The note also gives a new mailing address and two ways to send the author an online message.
