Saved answer files from the previous versions of DECnet-RSX are not sup­ ported. 2 New Features These are the major new features for this release: • LAT VS.l application terminals. Application terminal support allows DECnet-llM-PLUS and DECnet-Micro/RSX systems to access line print­ ers and other application devices connected through the Ethernet. First you must specify the remote server and port (or service) that a terminal created by the LAT Control Process will access. Then the application terminal issues a request for a connection, or it issues an I/O request that triggers the connection request. This causes the LA T process on the host to solicit a session with the remote terminal server. For example, the RSX system can access line printers connected to ter­ minal servers through the Ethernet. The user specifies the remote termi­ nal server and port (or service) that the queue manager will access. At the time of a print request, the print spooler initiates the request for a connection with the remote terminal server. For more information, refer to Chapter 6 of the DECnet-RSX Programmer's Reference Manual, Chapter 5 of the DECnet-RSX Guide to Network Management Utilities, and Section 9 of these release notes. • Proxy access. DECnet-lIM-PLUS and DECnet-Micro/RSX nodes sup­ port proxy. Proxy access gives a user access to an account on another node in the network without knowing the account name or the access con­ trol of the target account. The new Proxy utility sets up a proxy database that maps remote users to local accounts. NCP and CFE commands are used to enable and disable proxy on the local node. These commands control incoming access to a proxy account on the local node and out­ going proxy requests that are sent to other systems on the network. For more information, refer to Chapter 10 of the DECnet-RSX Guide to Network Management Utilities. • Extended length of access control information fields in connect blocks. The new implementation allows password, user name, and account lengths of up to 39 bytes each. Short connect blocks that use 8-byte passwords and 16-byte user names and accounts continue to be sup­ ported. For more information, refer to Chapters 2 and 3 of the DECnet­ RSX Programmer's Reference Manual. • New device support. Existing communication device drivers have been modified to support the new DHQll, DELQA, and DELUA devices. • Line and circuit counter timer support. Network management commands allow you to schedule and adjust the time interval at which counters for lines and circuits are logged to a file and automatically zeroed. This feature helps in network trouble shooting when hardware problems ex­ ist. For more information, refer to the DECnet-RSX Guide to Network Management Utilities. • Equal cost load splitting. Equal cost load splitting increases router per­ formance by using multiple paths over circuits of equal cost to route mes­ sages to a destination. CFE contains a new Executive parameter called MAXIMUM PATH SPLITS. This parameter defines the number of equal cost paths to use between a local and remote node. The default for path splits is 1, which disables path splitting. All nodes in the network must support receiving out of order segments if you want to use equal cost load splitting. For more information, refer to the DECnet-RSX Guide to Network Management Utilities. • Node identification in network management commands. Node iden­ tification format now supports wildcards. For example, you can use commands such as NCP SHOW NODE 2.* or NCP SHOW NODE *.*. • 802.3 support for DLX task-to-task LAN programming. A DLX task can allocate a data link port that processes incoming and outgoing frames ac­ cording to the IEEE 802.3 standard. The data link can filter data according to a Service Access Point (SAP) or Subnetwork Access Protocol (SNAP) identifier designated by the task. Refer to Chapter 4 of the DECnet-RSX Programmer's Reference Manual for more information. 2 3 Reporting and Isolating Problems A separate Software Problem Report (SPR) should be used for each problem. The separate reports simplify record keeping for quick responses. User problems are often difficult to reproduce. Therefore, in the SPR, please describe the system state when the problem occurred. Keep the description simple but accurate, and illustrate a general problem with several examples. When an SPR contains concise information about a
