This has nothing to do with this particular thread.
You should start a new Thread when you have a new question.

My question is if I can work with 8052 as serial data sender to the serial LCD or serial LCD just works properly with PC serial port?

IF you have a an LCD that works with a PC serial port, then you may be able to use the 8051's serial port.
But remember:
  • The 8051's serial port hardware only does 8-bit data, no parity; if your LCD requires anything else, you will need some software trickery.
  • A PC serial port is an RS232 port - therefore you will need an RS232 transceiver between your 8051 & LCD.

    I saw the 8052 serial signal in the osciloscope and there“s no serial signal there. My

    Obviously, with no signal you will get nothing on the LCD!
    First, you need to disconnect the LCD and find out why you are getting no signal!
