INTERIM_MEETING_REPORT_ Reported by Robert Moskowitz/Chrysler Corporation Minutes of the Telnet TN3270 Enhancements Working Group (TN3270E) The TN3270E Working Group met Thursday, August 26, 1993, at the Fall '93 INTEROP in San Francisco. Approximately thirty-four people attended, most were new faces. Bob Moskowitz, TN3270E Chair, presented a little background on the work started at the 26th IETF meeting in Columbus, Ohio, and what had been accomplished to date. The working group is well on the way of meeting its charter to produce three RFCs. 1. ``TN3270 Current Practices'' This one on current TN3270 practices is authored by Jon Penner; it is available as an Internet-Draft and is undergoing what is hoped to be final changes. 2. ``TN3270 Extensions for LUname and Printer Selection'' The Open Connect System's proposal for an interim printing solution is authored by Cleve Graves. It is also available as an Internet-Draft and is now undergoing what is hoped to be final changes. 3. ``TN3270 Enchancements'' This is a full redesign of the TN3270 protocol and is being authored by Bill Kelly. It is in its second version and the next is being worked on. The group does not feel that this document is finished; more customer and vendor input is needed. Cleve Graves followed with a presentation of his proposal. It quickly became apparent that a name was needed for this approach, and `Simple IBM Printing' or SIMP was proposed. The only addition suggested was support for IBM's Intelligent Printer Data Stream, or IPDS, and examples of how the query response would work. Cleve agreed that this was needed and committed to adding it. Cleve will also remove descriptive text that has found its way into the current practices document. He will work at getting the changes done quickly so this document can be moved on to full RFC status. Cleve's presentation was accompanied by a number of customer representatives' requests that this functionality be made available as soon as possible, if not yesterday, to meet their user needs. Based on this, everything will be done to get the document through the IETF/IESG system. Bill Kelly then presented the `Enhanced TN3270 protocol'. This protocol will be put forth as an IETF Standard and Bob explained the logistic steps involved in setting standards within the IETF. There was some concern about `breaking' the TELNET practice of negotiating Terminal Type first. With Enhanced TN3270, the new TN3270E option is negotiated before Terminal Type. Most of the attendees that understand TELNET did not see this as an issue. There was a side discussion on whether SNA positive and negative acknowledgments were needed and, if so, would SNA sequencing be needed in the protocol as well. No resolution of this point was reached. A question was raised about authentication and encryption. General agreement was reached that the TELNET authentication option will be used when possible, but that encryption will use the IBM SNA encryption methodology, thus making it not a TN3270 protocol issue. Finally there was discussion on expanding the protocol to include 5250 support. This was viewed by many of the vendors as an unwise burdening of the TN3270 protocol and that it would not bring any value either to it or to 5250 support, as the protocol issue is a very small part of either 5250 or 3270 emulation. However, it was agreed to spend some effort to investigate this. Bill wrapped up the presentation by stating that there are a number of changes that he will be making to the current document and that he will be calling on those attending to review his document and comment about it on the list.
