Abstract
L'invention concerne un procédé et un système permettant la transmission d'informations sous forme de texte par des signaux multifréquences. Un central transmet un premier signal multifréquence indiquant le début d'une transmission de texte. Un récepteur reçoit ledit premier signal multifréquence et se prépare à recevoir des informations sous forme de texte. Le central transmet au récepteur un deuxième et un troisième signal multifréquence à la suite du premier. Lesdits deuxième et troisième signaux contiennent des informations correspondant à un caractère de texte. Le récepteur reçoit lesdits deuxième et troisième signaux et détermine le caractère du texte transmis. Le central transmet un quatrième signal multifréquence au récepteur, indiquant la fin de la transmission de texte.
