Type into the terminal. If the characters you type appear on the screen, your adapter and drivers are working perfectly. If nothing appears, your adapter is faulty or the drivers are incorrect. 4. Correct the Power-On Timing Sequence
Floating ground loops introduce immense electromagnetic interference (EMI). This noise fills the UART buffer with random garbage bytes, prompting the "receive full" alert. 4. Adjust the Software Flow Control and Baud Rates Type into the terminal
