Abstract

PURPOSE: To secure the correct recognition of the operator for the actual data to be sent to the controlled side, by giving the echo-back to the data signal supplied through the keyboard toward the display part after securing the matching to the characteristics of the transmitted side.
CONSTITUTION: Fully double-type typewriter terminal unit 10 incorporates keyboard 16 and display mechanism 18. Converting device 12 is provided to carry out code conversion 22 and code reverse conversion 28 between the ASCII code to be used at unit 10 and the CCITT code to be used at the transmitted line connected to transmission line 14. In other words, the output data of reception part 20 is converted into the code of the transmitted side at code conversion part 22. Then this converted 22 code is applied to machanism 18 for display after reversely converted at 28. Accordingly, no display 18 is given to such character that exists in the ASCII code of unit 10 side and does not in the CCITT code of the transmitted side. As a result, the correct recognition is ensured for the data which is sent actually to the transmitted side.
