ABSTRACT:
The invention relates to a terminal controller for editing formatted screen data sent from a processing unit to produce edited screen data and for transferring the edited screen data to a terminal device. The edited screen data which can be repeatedly used is stored in a buffer memory which is separately provided in the terminal controller. In response to a command from the processing unit, this data is extracted from the buffer memory so that the screen data is transferred to the terminal device without being re-edited for each transfer. The data stored in the buffer memory is subjected, if desired, to a synthesizing processing before it is sent to the terminal device.
