In a method for the management of a communications module on a telephony network, the module is connected to a terminal that is incapable by itself of getting connected to the telephone network. The module has a tool kit microcircuit whose management is shared between the module and the terminal so as to limit communications on a link between the module and the terminal. The module and the terminal exchange messages in the HAYES format in order to standardize an interface between the module and the terminal. The messages exchanged are command messages, responses to commands, or general information on the state of the device.
