About LCD question

I use the STONE display module. But I cannot communicate with the module using UART. I tried different serial port applications like SSCOM, RealTERM, SerialPlot but nothing changed. When I sent this command: 0xA5 0x5A 0x04 0x80 0x03 0x00 0x01 to display using SSCOM with PC, there is no response from display. In my project, I have a 1.JPG file. I don’t know what went wrong.
