Changes

BTX (Bildschirmtext, translated as Screentext) has been a german German service, allowing to transfer data via telephone line. In the 8bit era, the Deutsche Bundespost (german German postal service) still owned the monopoly for telecommunications in germanyGermany, so the only (legal) way to transmit electronic data via telephone line has been to use their BTX service. The service was ultimatively suspended in 2007.
