Why does AT command don't work with ESP8266-01?

i have a problem with my new ESP01. I tried using AT commands with the baud rate of 115200, but don't receive OK answer. I also tried to flash it and didn't quite succeed as it's just flashing that never ends (treid for about 10 minutes).

Setup I use:

  1. ESP8266-01
  2. USB A to UART
  3. TeraTerm

What I get:

  1. When baud = 74880:

Solution
