TM4C123GH6PM: uart not sending all chars only 2 are sent

hello , i recently bought a node mcu with esp8266 wifi module and i was trying to get it to communicate with my tiva c microcontroller , i was trying to send a simple sentence dofile("script1.lua") which should make the led on the node mcu to blink , sending this via a serial monitor using putty works on the node mcu with no issues , however using the micrcontroller with the same settings as putty doesnt work in fact when both the microcontroller and the nodemcu are connected through usb on my laptop i can see that only 2 letters are being sent , d and o the first 2 letters in my sentence nothing else is being sent , any idea what might be happening with my tiva c ? 

here is the full code i am using to send the dofile like and then waiting if anything is received from the node mcu
