Abstract

The invention relates to a system for remotely monitoring equipment which makes it possible to interconnect at least one server and at least one remote equipment according to a predetermined protocol. The inventive system is associated with at least one remote equipment of radiocommunications means emitting and receiving AT instructions emitted by and/or destined for an external application carried out by said remote equipment. Said means is provided with a set of specific instructions making it possible to manage the data exchange between said remote equipment and at least one server performing said protocol, wherein at least one of said instructions enables said radiocommunications means to produce, modify and/or to send format XML pages.
