Abstract: In order to track activities in a computerized system with client-server or other communications, a system configuration is needed which monitors, logs and reports traffic. This is somewhat akin to but not entirely similar a firewall. Thus, the invention contemplates a real-time, platform-independent, rule-based activity monitor for detecting a particular activity of interest as it occurs and for reporting such activity and the user substantially as fast.

Abstract: A method of identifying computer screens is disclosed. The method is particularly useful in identifying IBM host screens in script creation and playback. According to the method, a signature is composed for a given screen. The signature comprises characteristics of a given screen which differentiate that screen from substantially different screen displays. For an IBM host screen, signature composition is based upon the screens protected fields. The protected fields are further processed by removing transient information such as the date and time.

Abstract: A terminal emulation program for an IBM host is described. The program can record scripts (mini-programs) of IBM host sessions. For each action or event, as desired, the program records an appropriate script. Scripts may be created for connecting to and disconnecting from the IBM host, for sending key strokes, for sending playback-time inputs, for awaiting a certain screen, and for importing displayed IBM host data. The scripts are stored in a file on a PC and may be replayed either from the terminal emulator, from Windows, or via OLE.

Abstract: Control of the transfer of data objects over a communications link is achieved by obtaining a representative data object having an object size and a transfer time over the communications link. The object size of the representative data object is determined. The transfer time of the representative data object is determined. An effective transfer rate for the communications link is determined using the transfer time and object size. The effective transfer rate is compared to a predetermined value. A number of transfers to perform concurrently is determined based upon the comparison.
