ESP8266 serial interface baud rate

I have acquired some ESP8266 chips, in the 12S version. I remember working with an earlier ESP 8266, but you had to guess until you found the default baud rate. I found one comment on the internet that said the default for the 12S is 9600. Can anyone verify that?

Thanks in advance for any help.

To communicate with Esplorer i use 9600
For flashing 19200

You can safely try other baudrates if you connect with Esplorer it report the firmware version if the baudrate is correct.

For the flashing it will hang if the baudrate is wrong but you can restart the flashing.
