Abstract: Presumptive option negotiation is provided between a first entity and a second entity, each of which is operative to communicate according to a communications protocol including a plurality of negotiable options. A first information transfer from the first entity to the second entity is performed according to the communications protocol, the first information transfer including a message indicating support of an option and a message conforming to the option. A second information transfer from the second entity to the first entity it then performed according to the communications protocol, the second information transfer including a message indicating support of the option and a message responding to the message conforming to the option.

Abstract: A technique, system, and computer program for using a database to store program logs. Logged information can be created, stored, displayed, and analyzed in a more usable, efficient manner. Log information is preferably stored in two or more tables, enabling reduction of redundant information through database normalization. Message text is preferably stored in computer-readable, as opposed to human-readable, format. This enables optimization of the amount of storage required, and facilitates normalizing the database tables. In addition, translation to the user's national language is made easier, whereby a message code is stored, pointing to an entry in a table that contains message text in the chosen language. The report-generating facilities of the database manager are available for use in analyzing log entries, eliminating the need to write customized reporting software.

Abstract: A method of communicating between computers, particularly between a host connected to a network server, and a workstation client running a terminal emulator. A pre-warmed cache is generated, containing information used in common by emulation programs on the client and server. The pre-warmed cache can be loaded on the client, e.g., when establishing a session with the server. The pre-warmed cache may be generated by executing an application on the host, transmitting at least one terminal data stream associated with the application to the server (or to a second server configured substantially similar to the first server) and building a cache instance using one or more portions of the terminal data stream. A single pre-warmed cache can be provided for different hosts.

Abstract: A session is established between a terminal and host, each of which are operative to communicate according to a communications protocol. A communications channel is established between the terminal and the host via a client and a server of a communications network, the client being connected to the terminal and the server being connected to the host. Terminal type information is communicated from the client to the server via the communications channel. An indication of readiness to communicate data between the terminal and the host is communicated between the server and the client via the communications channel.
