 Steps:
 
-- Make sure UART_FIFO_CAPACITY in the CONFIG proc is set to 253.
 - Start the mlogv32-utils socket server.
 - Run each of the following commands in a separate terminal (replace `127.0.0.1` with your [host ip](https://learn.microsoft.com/en-us/windows/wsl/networking#accessing-windows-networking-apps-from-linux-host-ip) if using WSL):

 - Build and flash this program to mlogv32, then start the processor.
