I appear to have flash .91. and had success (80% of the time). the following changes were made
1) Serial is 115200 only
2) RST pin needs to be high on the newer models (as documented in the dragon elect)
3) setup voltage divider UnoR3 TX -> 1K -> ESP RX -> 2K -> GND
once these were done, I got the proper response

The timings in the original sketch are all wrong! The arduino does not properly pick up the OK some times and there is no check to see if the module is waiting or busy.
Got a full html return from google searching for "lol"
Built a proper test shield with 3.3v regulator and voltage divider.
had to pull up the enable pin with 3.3v
