Function serial_read

src/serio.rs:410–413

Retuns the current buffer of data the serial interface has accumulated. You can interact with this buffer, modify it, etc. It is recommended to call `.clear()` on the buffer as soon as you are done with the data, otherwise the buffer will eventually overflow.

(device: SerioDevice)

/// done with the data, otherwise the buffer will eventually
/// overflow.

    let uart = get_uart_interface(device);
    return uart.get_rx_buffer();
}

/// Returns the amount of data in the currenet read buffer.
pub fn serial_available(device: SerioDevice) -> usize {
