Abstract: A cellular telephone instrument having a plurality of SIM card slots has a plurality of SIM cards inserted, each of the SIM cards identifying a corresponding one service identity distinct from service identities identified by others of said SIM cards, and a control element in the instrument enabling selection of one of the plurality of service identities and effectuating operation of the instrument under the selected service identity.

Abstract: An e-mail software program is provided with an exclusionary function which removes the name of a sender from a list including the sender before forwarding a message received from the sender to others on the list. On receiving an e-mail message, the name of the sender is saved and subsequently deleted from the list of recipients to which the message is forwarded. The function is invoked by activating a button provided in the graphical user interface (GUI) of a recipient computer.

Abstract: A system and method for providing obscured output from a data processing a system to allow analysis of the output without disclosing sensitive information. In response to an error condition, selected portions of the data being used in the data processing system are replaced by means of an irreversible algorithm to obscure the data, then the data processing is repeated with the obscured data to determine that the error still exists with the obscured data. If the error ceased to exist when one substitution technique is used, the process is repeated with a different technique in an attempt to find a substitution system which repeats the error while masking the data, allowing analysis of the files and correction of the error without divulging the information.

Abstract: An adapter for providing data communications for a personal computer to other remote data communications systems of various communication platforms is disclosed. The remote data communications systems can be a data circuit terminating equipment (DCE) such as a modem, or a data terminating equipment (DTE) such as an ISDN terminal adapter. The adapter comprises a programmable digital signal processing device, a memory device and an assortment of transceiving devices. A software program is stored in the memory device for instructing the programmable digital signal processing device. The transceiving devices are controlled by the programmable DSP device such that the appropriate transceiving device can be activated for providing data communications, according to the type of communication platform utilized by the remote data communications equipment.

Abstract: A merchandise order entry system is provided with a multi level order entry screen. The screen includes one or more profile fields each of which can have different order parameters such as different credit card numbers, and bill to and ship to addresses. A remote user can, in addition to entering orders, edit, delete or create profile fields.

Abstract: A method, apparatus and article of manufacture are described. In particular two network interface devices that are connected over a path that includes a digital trunk using robbed-bit signaling use a technique to identify the presence of robbed-bit signaling. The network interface devices synchronize to bytes that are subject to robbed-bit signaling. The network interface devices must synchronize to the robbed-bit signaling to avoid transmitting information or receiving information in these signaling positions. The network interface devices then take advantage of the least significant bit positions of frames that are not used for robbed-bit signaling. This results in an increase in data carrying capacity from 56 kps to 62.7 kps.

Abstract: When two 56K server modems communicate with one another over the public switched telephone network, they signal each other so that they communicate data to each other in a digital pass-through mode whereby essentially there is a direct digital connection between the two modems. This is accomplished by using extended ITU-T Recommendation V.8 protocols.

Abstract: A method, apparatus and article of manufacture are described. In particular two network interface devices that are connected over apath that includes a digital trunk using robbed-bit signaling use a technique to identify the presence of robbed-bit signaling. The network interface devices synchronize to bytes that are subject to robbed-bit signaling. The network interface devices must synchronize to the robbed-bit signaling to avoid transmitting information or receiving information in these signaling positions. The network interface devices then take advantage of the least significant bit positions of frames that are not used for robbed-bit signaling.

Abstract: A method of indicating a state of progress of a task being processed in a computer system by providing a progress-indicating visual pointer on a display device of the computer system. Prior art visual pointers (such as an arrowhead) are responsive to a pointer device such as a mouse, and are used to manipulate features of a graphical user interface (GUI). These prior art pointers do not indicate the state of progress of a task underway, but rather only indicate that the task is still running. The progress-indicating pointer of the present invention can take the form of a wristwatch or clock icon having a face which is filled, e.g., in a clockwise fashion, or the form of an hourglass icon having a portion, e.g., the lower half of the hourglass, which is filled in an amount proportionate to the state of progress of the task being processed. The different states of the icon can easily be presented by providing a plurality of bitmaps (e.g.
