Abstract: A switch is provided that detects when a computer expansion card has been added, removed or changed. During operation, the switch is held in a depressed position by contact with a card. If the card is removed, the switch is raised and, when a second card is installed in the same slot, the switch is again depressed. The depression of the switch triggers a change signal that initiates the introduction of power to the slot for a period of time long enough for the hypervisor to detect the new device. A delay between a release and subsequent depression of the switch is measured such that when the switch is released enough time is provided to firmly seat a different card in the planar device. Following the delay, power is supplied to the slot so that the hypervisor detects the card and updates the current configuration parameters.

Abstract: Methods and arrangements of monitoring applications active on a plurality of computers are discussed. Embodiments include transformations, code, state machines or other logic to connect a plurality of computing devices via a keyboard video mouse (KVM) switch and to detect applications active on the computing devices. In some embodiments, each computing device may be connected to a display separate from the KVM switch. The embodiment may include detecting applications signaling a user for attention and displaying a list of active applications of the plurality of computing devices in response to a command from the user. The displaying may include giving priority to the applications signaling a user for attention.

Abstract: Disclosed is a method, system, and computer-readable medium with executable code for viewing the operation of multiple client terminals from a single user interface of a server terminal. A buffer sharing logic of the server terminal and the client terminals is used to transmit and receive display data between the computers. The server terminal may use buffer sharing logic to cycle between desktop views or program windows of processes running on the connected client terminals. A user of the server terminal may select to view program windows of processes running on the connected client terminals, or a virtual extended desktop of the server terminal and connected client terminals. Once a program window or virtual extended desktop is chosen, the user of the server terminal may view the client terminal screen where the chosen desktop or window resides.

Abstract: Disclosed is a method, system, and computer-readable medium with executable code for controlling the operation of multiple client terminals from a single keyboard and mouse of a server terminal. A buffer sharing logic of the server terminal and the client terminals is used to transmit and receive user input between the computers. The server terminal may use buffer sharing logic to cycle between desktop views or program windows of processes running on the connected client terminals. A user may use an ALT-TAB command to select a desktop view or program window of a connected client terminal. Once a screen or desktop is chosen, the user of the server terminal give focus of the selected application on a display connected to the server terminal. Additionally, the buffer sharing logic allows the user to dynamically copy and move data between the computer terminals at will.
