Communication system and data adapter

摘要

The invention relates to a communicating system comprising a data terminal (3), a wireless communication device (2), and data transmission means (M1, M2, M3, MX) for setting up a local data transmission connection between the data terminal (3) and the wireless communication device (2). The data transmission means (M1, M2, M3, MX) comprise the data transmission means (M1, M2, M3) of the data terminal and the data transmission means (MX) of the wireless communication device. The data terminal (3) comprises means (11, 13) for running application software, an application software connection (14), means for controlling the data transmission means (M1, M2, M3) of the data terminal, and a first connection interface (15) for data transmission between the application and the application programming interface (14). The data transmission system comprises also a data adapter (12), a second connection interface (16) for data transmission between the application programming interface (14) and the data adapter (12), and one or several media interfaces (17a, 17b, 17c) for data transmission between the data adapter (12) and the data transmission means (M1, M2, M3) of the data terminal.
