There is nothing like enable/disable echo mode on a serial port.
You have to have a program that has opened the serial port and when data is received the program sent it back.

If it is for testing to check if the serial port works, you can buy a serial loop back adapter that you plug in to the serial port.

But in Linux you would find ECHO options with clflag to enable/disable the echo mode. whats the alternate for it in windows

I do not think it is possible in Windows. The SetCommState function does not mention ECHO mode.
