Abstract
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 the server; and (iii) a dialer application for establishing an upstream connection using the upstream device driver, the present invention initiates a connection in response to upstream traffic generated by an application including the steps of receiving the upstream traffic in the downstream device driver; constructing a dial packet in the downstream device driver in response to the upstream traffic; transferring the dial packet from the downstream device driver to the dialer application; and, issuing a call command to the upstream device driver.
