Help for MQTT setup with ESP8266

Hey! I want to setup Mqtt Communication with ESP 8266 using AT commands… But as you know I need to send Some pre-commands like Connect, Pub, and Subscribe with username and password to establish MQTT Communication. But Some of the ASCII characters like EOL, Null, Escape etc. Which I can’t send in the terminal of ESP 8266.But when I convert them to hex it’s easy to send them… So for this I need two help… First tell me terminal where I can directly send Hex Characters… Second how to use AT commands to setup this communication…

If you followed by previous tutorial on MQTT, it shows how to do this exactly and which terminal to use (Hercules/TMFT).
And the AT commands will remain same for SIM900/SIM800 or ESP8266, Only addition will be the Wifi connection AT commands, Most of the commands will remain same. I will make a tutorial on it in coming week.

TMFT and hercules can handle any character to be sent. Just send he hex values for EOL. 0x0A and 0x0D
