Cant connect nano esp8266

Hi I have established my esp8266 is working by following this guide How To Connect Arduino + ESP8266 To Cayenne - YouTube
when I open the cmd prompt and navigate to scripts I get a slightly different response to the guide

At this point I get stuck, no connection, any suggestions would be great

The output from the serial connection looks fine. I watched the video and I’m not sure why they are using the USB modem script if they are using an ESP8266 as a wifi shield. The ESP should be handling the connection. take a look at this thread and let me know if it helps.
