Abstract
PURPOSE: To monitor easily data from an external computer, by providing a switch, an input gate, and a controlling character generator and displaying the control code and the dummy code from the external computer on the screen of a display part as symbols.
CONSTITUTION: When receiving data 1 shown in figure M is sent from an external computer under the state where a changeover switch 31 is made, a display controlling part 3 detects that a signal (a) of a gate 33 is in the low level, and the controlling part 3 writes the control code and the dummy code such as STX and ESC in a refresh memory 4 as codes as they are. This data 1 is read out from a timing circuit 7, and display codes such as A, B, and C are converted to dot patterns by a character generator 5 and are displayed as video signals on a display part 8. Meanwhile, the control code such as STX is converted to a dot pattern by a controlling character generator 51 and is displayed on the display part 8. When the switch 31 is broken, the controlling part 3 writes only display codes in the memory 4.
