Abstract
An applications program is provided for permitting a user of a host processing system to dynamically control a modem having forward compatible and expandable functionality. In a preferred embodiment, the applications program is designed to run on a personal computer running the Windows.RTM. shell, and the modem is compatible with ADSL promulgated standards. As part of such program, initialization and detection routines determine the capabilities of an ADSL modem, including whether the same has been upgraded to have enhanced data throughput. A calibration routine measures the computing power available to the host processor, and based on this information and other relevant parameters determines nominal setup parameters for the modem. These parameters are stored in a Device Parameter Table so that they can be accessed by various application programs that may make use of such modem. A user of such program can at that time or thereafter alter the characteristics of the ADSL modem (including a target data rate) subject to availability of sufficiently powerful analog front end sampling circuitry and processing power.
