[Coco] WiFi modem.

[Dave Philipsen]

That's interesting stuff, Allen.  The "stock" firmware of the ESP8266 
uses an AT command set but the actual commands are much different than 
the Hayes modem.  So I have a couple of questions: 1) How do you update 
the firmware on the ESP8266?  2) Are all iterations of the ESP8266 the 
same as far as firmware updates?

I have a few of the ultra-cheap Chinese eBay ESP8266 boards but I've 
noticed that there are some other slightly different designs out there too.
