I am sittting in Beijing and have bought some ESP8266 modules and I have several years experience in MCU and serial data development.
The modules are powered from a good supply and I have a USB-3.3V TTL converter connected.
Ch_PD is 3.3V
GPIO 0 connected to GND
TX and RX connected
GND and VDD connected.
I have also tried to start up the module with GPIO 0 unconnected but the data string from the module remains the same..
When I turn on the power the red led turns on and I can see a quick flash of the blue led. My serial terminal software is set up to 74880 baud and the serial communication the module sends out is below

waiting for host
I can not get the module to accept any AT commands and I can not get the module to communicate with any firmware upgrade PC application. Ihave also used a logic analyzer to see the and the module does not respond to anything.
Could anyone please tell me what I am doing wrong?
