Abstract: A method and computer system according to the disclosed invention allows the pre-installation of a software application without a license key. The computer system installs a software application and provides a prompt for a license key. The license key is stored in a registry. If the license key is not entered, the computer system installs the software application and installs disabling code. At startup, the disabling code is executed if installed, providing a prompt for a license key. If the proper license key is entered, the computer system stores the key in a registry and uninstalls the disabling code, allowing installation of the software application. If an improper key is entered, the computer system allows the key to be reentered.

Abstract: A computer system implements a standard modem without the use of a microcontroller. Instead, a digital signal processor is provided on an expansion card, but with direct links to the computer system itself. The code usually implemented in the microcontroller is instead implemented as a virtual modem controller to be called by the operating system of the computer itself. Further, this virtual modem controller includes a virtualized UART, that appears to the operating system software as a hardware UART, with entry points for calls to replace input/output instructions. In this way, standard device driver code written to execute input/output operations is easily converted to operate with the “virtualized” UART.

Abstract: A method and apparatus for increasing system functionality through a predefined interface is disclosed. Signal lines which are not used or which are not used in certain modes are connected to an interconnection device instead of being connected to an interface wherein the output of the interconnection device is connected to the interface where such lines would have been connected. The interconnection device also has a set of inputs for receiving signals from a device providing the desired functionality. A controller chooses between the two sets of inputs to control what signal lines are connected to the predefined interface. Accordingly, during certain modes of operation, the added functionality from a device whose output is being switched into the interface can be supported. In one embodiment, speaker phone capability is provided for even though the predefined PCMCIA interface does not support such capability.
