  • Method for connecting a plurality of communication applications with an actual communication port by emulating a plurality of virtual modems
    Patent number: 6012113
    Abstract: The present invention provides for a virtual modem device for connecting to a plurality of active communication applications in an environment wherein communication applications utilize a communications driver when talking to an actual modem attached to the system. The virtual modem device selectively connects the communication applications to an actual modem, handles and connects incoming calls to the appropriate communication application, and provides for direct connection capability. The invention utilizes a software communications driver and a master communications application to control the driver connectivity to fool each communication application that it is connected to the actual modem. The virtual modem is implemented by creating a communications driver in software that emulates a modem in idle mode (e.g., when it is not off-hook and in command mode) and is utilized for each communication application that is connected to a communication port designated as a virtual modem.

  • High-speed transfer of data between a PC compatible microcomputer and a bus device
    Patent number: 5680553
    Abstract: A method for the high-speed transfer of data between an IBM compatible personal computer (PC) and a bus device. A DMA controller is placed on the bus device to by-pass the PC's DMA controller. High-level terminate and stay resident software on the PC uses a combination of the DMA controller on the bus device and low level DMA controller routines to transfer the data between the PC and the bus device.
