why does usb serial prints unreadable �? identify your usb's BAUD `stty -F /dev/ttyUSB0`

baud.go

package main

import (
	"bufio"
	"fmt"

	"github.com/tarm/serial"
)

func main() {
	c := &serial.Config{Name: "/dev/ttyUSB0", Baud: 115200}
	s, err := serial.OpenPort(c)
	if err != nil {
		fmt.Println(err)
		return
	}

	scanner := bufio.NewScanner(s)
	for scanner.Scan() {
		fmt.Println(scanner.Text()) // Println will add back the final '\n'
	}
	if err := scanner.Err(); err != nil {
		fmt.Println(err)
		return
	}
}
