Abstract: The document processing system which performs a function of storing in a memory data of a bracket input by an input device and positional data of starting and ending points of the bracket located in the document. The document processing system then determines an appropriate size of the bracket based on the positional data stored in the memory so as to properly lay out the bracket in the document. The system then generates and displays the appropriately sized bracket in a position specified by the positional data.

Abstract: A data communication apparatus includes a data communication portion adapted to be connected to the public telephone line in parallel to a telephone set for data transmission/reception with another station through line connection, a termination command generating device for generating a termination command to terminate data communication by the data communication portion under predetermined conditions, a detecting device for detecting a termination command and generating a detection signal, a delay circuit for delaying the detection signal by a predetermined time, and a line connection terminating device responsive to the delayed detection signal for terminating line connection. There is a predetermined time margin defined by the delay circuit, during the time the termination command is generated until the line connection is terminated.
