对于一个终端设备（PC），其优选通过传输链路（FL），特别是电传线和远程订户设计为个人计算机连接在端子（PC）之间和所述传输链路（FL）传输单元之间传输数据（UE） 提供，在其上还打印机终端（PC）的（DR）连接。 传输单元（UE）包含除了一个发送/接收单元（SE）具有控制单元（ST），其设有一个切换单元（UM），无论是由终端（PC）在本地操作模式数据（D）发射的，或通过 所述传输链路（FL）传输的供给作为输出单元的打印机（DR）的数据（SD，ED）。 此外，控制部（ST），也没有存储单元（LS，PS），以及代码转换器（CW1，CW2）包括在内。

For transmitting data between a terminal (PC), which is preferably designed as a personal computer via a transmission link (FL), particularly a telex line, and a remote subscriber is connected between the terminal (PC) and the transmission link (FL) a transmission unit (UE) provided, on which also the printer (DR) of the terminal (PC) is connected. The transmission unit (UE) contains in addition to a transmitting / receiving unit (SE) has a control unit (ST), which is provided with a switchover unit (UM) to either emitted by the terminal (PC) in a local operating mode data (D) or the above the transmission link (FL) transmitted data (SD, ED) to the printer (DR) to supply as an output unit. In addition, the control unit (ST) nor storage units (LS, PS), and code converters (CW1, CW2) included.
