Mine is on the NodeMCU firmware by default. I connected to it using picocom /dev/ttyUSB0 and by pressing the RST button I get this output :

Hello World

picocom -b 115200 --omap crcrlf /dev/ttyACM0 where /dev/ttyACM0 is my arduino UNO used for powering the Module and UART(~RS232). I found the baud rate on Playing With a ESP8266 WiFi Module

A easy test you can do is to type AT and return, it should give you OK, like this (boot banner included):
