An electronic communication notepad including a touch-sensitive screen (1) addressable pixel by pixel by means of a stylus, and a data management microprocessor linked to a ROM and RAM memory. The stylus and a set of keys are used to create graphic and text messages for transmission by a combination of a mains carrier current (10) and a telephone network to remote notepads via a carrier current modem (8) and a switcher unit (12) operating as the interface between the carrier current (10) and the telephone network. The addressee may thus instantly and discreetly reply to a displayed message by actuating a set of hand- or foot-operated contactors (16) according to a predetermined code. |
