 BTX (Bildschirmtext, translated as Screentext) has been a German service, allowing to transfer data via telephone line. In the 8bit era, the Deutsche Bundespost (German postal service) still owned the monopoly for telecommunications in Germany, 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.

-Schneider BTX module for the CPC. The hardware design is based on an universal BTX decoder made by Siemens. It is connected to the CPC's expansion port and additionally hooked in between computer and monitor. The module must also be connected to a BTX modem with a D-BT 03 port. These modems were provided by the Deutsche Post and had to be returned after use, because the BTX subscriber ID was hard-coded within the device.
