  58. <p>Mine is on the <a href="https://nodemcu.readthedocs.io/en/master/">NodeMCU</a> firmware by default. I connected to it using <code>picocom /dev/ttyUSB0</code> and by pressing the RST button I get this output :</p>
  59. <code><pre>NodeMCU custom build by frightanic.com

  71. <code>picocom -b 115200 --omap crcrlf /dev/ttyACM0</code> where <code>/dev/ttyACM0</code> is my arduino UNO used for powering the Module and UART(~RS232). I found the baud rate on <a href="http://williamdurand.fr/2015/03/17/playing-with-a-esp8266-wifi-module/">Playing With a ESP8266 WiFi Module</a>
  72. <p>A easy test you can do is to type <code>AT</code> and return, it should give you <code>OK</code>, like this (boot banner included):</p>
