 When flashing, with `esplash`, you will be prompted to select a USB port. If this port is always the same, then you can also pass it as a parameter on the command line to avoid the prompt. For example if
 `/dev/ttyUSB1` is the device file for your port, the command line changes to `espflash --monitor /dev/ttyUSB1 path/to/binary/to/flash_and_monitor`.
