If this buffer becomes full (for example, if no PC Terminal is connected), the ESP32 will do a one-time wait of 50ms hoping for the PC Terminal to request the data.

This is in contrast to using a USB-to-Serial (UART) bridge chip, which will always ingest the bytes and send them to a (possibly not listening) ESP32.
