Okay. I shall look it up. By the way, i did confirm the working of the UART pins(UART1 RX to UART4 TX and vice versa). I had two terminal tabs open and when i typed into one and entered(UART1 settings) it showed up on the other terminal with UART4 settings. I inferred that the Adafruit libraries work just fine for the BBB (correct me if i am mistaken)
It is just that while interacting with a CNC machine(with a HAAS OS) it is not communicating rather just showing up what is being sent.
