[![Build Status](https://github.com/rust-osdev/uart_16550/workflows/Build/badge.svg)](https://github.com/rust-osdev/uart_16550/actions?query=workflow%3ABuild) [![Docs.rs Badge](https://docs.rs/uart_16550/badge.svg)](https://docs.rs/uart_16550/)

Minimal support for uart_16550 serial output.

## Usage

```rust
use uart_16550::SerialPort;

const SERIAL_IO_PORT: u16 = 0x3F8;

let mut serial_port = unsafe { SerialPort::new(SERIAL_IO_PORT) };
serial_port.init();

// Now the serial port is ready to be used. To send a byte:
serial_port.send(42);
```
