Struct SerialPort 

pub struct SerialPort(/* private fields */);

A x86 I/O port-mapped UART.

Implementations

impl SerialPort

pub const unsafe fn new(base: u16) -> Self

Creates a new serial port interface on the given I/O base port.

This function is unsafe because the caller must ensure that the given base address really points to a serial port device and that the caller has the necessary rights to perform the I/O operation.

pub fn init(&mut self)

Initializes the serial port.

The default configuration of 38400/8-N-1 is used.

pub fn send(&mut self, data: u8)

Sends a byte on the serial port. 0x08 (backspace) and 0x7F (delete) get replaced with 0x08, 0x20, 0x08 and 0x0A (\n) gets replaced with \r\n. If this replacement is unwanted use SerialPort::send_raw instead.

pub fn send_raw(&mut self, data: u8)

Sends a raw byte on the serial port, intended for binary data.

pub fn try_send_raw(&mut self, data: u8) -> Result<(), WouldBlockError>

Tries to send a raw byte on the serial port, intended for binary data.

pub fn receive(&mut self) -> u8

Receives a byte on the serial port.

pub fn try_receive(&mut self) -> Result<u8, WouldBlockError>

Tries to receive a byte on the serial port.

Trait Implementations

impl Debug for SerialPort

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Write for SerialPort

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
