   = note: in the 2018 edition `try` is a reserved keyword, and the `try!()` macro is deprecated
help: you can use the `?` operator instead

extern crate serial;

use std::io::prelude::*;

fn main() {

    port.reconfigure(&|settings| {

    })?;

    port.set_timeout(Duration::from_millis(1000))?;

    let mut buf: Vec<u8> = (0..255).collect();

    port.write(&buf[..])?;
    port.read(&mut buf[..])?;

    Ok(())
}

Use the ? operator
