  • Real-time communications gateway
    Patent number: 9648052
    Abstract: A system performs Real-Time Communications (“RTC”). The system establishes a signaling channel between a browser application and a rich communications services (“RCS”) endpoint. The system then queries RCS capabilities of the RCS endpoint via the signaling channel, and initiates the RTC between the browser application and the RCS endpoint via the signaling channel.
    Type: Grant

  • Network communications subsystem and method for digital computer system employing protocol stack having diverse lower-level network driver components optimized for each of base and enhance operating systems
    Patent number: 5802307
    Abstract: A communication subsystem for a digital computer system, which processes application programs under a base operating system (such as the MS-DOS operating system) in a first processor operational mode (such as the V86 mode), and also under an enhanced operating system (such as Microsoft Windows) during a session under a second processor operational mode (such as a privileged or user mode). During an enhanced operating system session, the enhanced operating system makes use of at least some selected elements of the base operating system, in particular relation to the current invention some of the communications drivers. The communication subsystem enables the digital computer system to transfer messages, each comprising a series of characters, over a communications network.

  • Method for automatically transitioning from V86 mode to protected mode in a computer system using an Intel 80386 or 80486 processor
    Patent number: 5255379
    Abstract: A method for transitioning an Intel processor from virtual 8086 (V86) mode to protected mode operation which detects when a virtual V86 processor attempts to transition to protected mode, stores all of the information concerning the virtual processor at the time of the attempt to transition to protected mode, remaps the memory allotted to the virtual processor to the memory space used in running a process in real mode, sets up a dummy stack to provide for operation during a transition to protected mode, moves a process for transitioning to real memory space, shifts all of the register values to values for real memory space, and finally reactivates the transition to protected mode.
