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. The first information transfer may include transfer a message indicating support of a terminal type negotiation option and a message conforming to the terminal type negotiation option, and the second information transfer may include transfer of a message indicating support of the terminal type negotiation option and a message responding to the message conforming to the terminal type negotiation option. The communications protocol may include a Telnet or other option-negotiating protocol. Data communications systems, apparatus and computer program products for employing the above-described presumptive negotiation functions are also described.

Systems, methods and computer program products for employing presumptive negotiation in a data communications protocol

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.

Using a database for program logs

Construction and usage of a pre-warmed cache for client-server emulator

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. Messages are communicated between the client and the terminal and between the server and the host according to the communications protocol to emulate communication of session establishment messages operative to establish a session between the terminal and the host according to the communications protocol without requiring communication of the session establishment messages via the communications channel. Related apparatus and computer program products are also discussed.
