A data communication system is configured to communicatively link a host device and a client device with a point-to-point data communication link, where the point-to-point data communication link is configured with multipoint network data communication components designed for data communication over a distributed network. A data communication interface at the host device is communicatively linked with a data communication interface driver via the point-to-point data communication link between the host device and the client device. The data communication interface driver communicates with a virtual driver component for the client device via a virtual network at the client device.

Methods and apparatuses are provided that allow kernel mode data traffic and user mode data traffic to share a common network communication port. One apparatus includes user mode logic, kernel mode logic, and kernel mode to user mode interface logic. The interface logic is configured to receive data packets and selectively distribute the data packet to either the user mode or kernel mode logic. The interface logic includes 'virtual' bridge logic and 'virtual' miniport logic. The bridge logic determines if a received data packet is a user mode or kernel mode data packet. If it is a kernel mode data packet, then the bridge logic provides the data packet to the kernel mode logic. If it is a user mode data packet, then the bridge logic stores the data packet in memory for subsequent use by the user mode logic. The bridge logic also receives outgoing kernel mode data packets from the kernel mode logic and provides them to a network communication port, and retrieves outgoing user mode data packets from memory and provides them to the same network communication port. The miniport logic provides an interface between the memory accessed by the bridge logic and user mode logic. The miniport logic accepts outgoing user mode data packets and stores them in the memory for subsequent access by the bridge logic, and retrieves incoming user mode data packets stored in memory by the bridge logic.

A mechanism that reduces power consumption of a transmitter/receiver circuit in a wireless device. The transmitter/receiver circuit is powered down to a reduced-power state after transmitting a message. The reduced-power state is too low to be able to transmit or receive information. Round trip statistics regarding how low it typically takes to receive a response to the message are then used to determine when to power up the transmitter/receiver circuit to the extent that it could receive the response. Accordingly, by being powered up for only a window of time in which the receipt of the response would likely occur, the transmitter/receiver circuit consumes less power while still likely receiving the response. The window of time may be adjusted as appropriate for the importance of the information, the performance of the specific wireless network, and the sensitivity of the wireless network to not receiving the response.
