1. In a client having (i) an upstream device driver for controlling an upstream device which sends data to a server;

  • (ii) a downstream device driver for controlling a downstream device which receives data from said server, said upstream device driver and said downstream device driver being separate drivers for separate devices; and

    (iii) a dialer application for establishing an upstream connection using said upstream device driver, a method for initiating a connection with said server in response to upstream traffic generated by an application in said client comprising the steps of;

    receiving said upstream traffic in said downstream device driver, said downstream device driver being incapable of transmitting said upstream traffic;

    constructing a dial packet in said downstream device driver in response to said upstream traffic;

    transferring said dial packet from said downstream device driver to said dialer application; and

    ,issuing a call command to said upstream device driver.
