Abstract

A system and method for implementing an arbitrary protocol such a voice/data multiplexing protocol using a generic modem and protocol software running on a host computer. An existing server-modem may support a special-purpose protocol such as voice and data multiplexing for a virtual presence application. A client computer may access the dedicated server-modem using a standard modem having a standard program interface, especially a V.80 modem, while the corresponding client-side protocol is implemented in software on the client computer. In particular, a virtual presence protocol may be implemented in software on the client computer and may interface to the standard program interface of the client-side modem.
