Go에서 While 루프를 사용하여 연속 직렬 포트 데이터 읽기를 달성하는 방법은 무엇입니까?

<code class="go">package main

import (
    "fmt"
    "github.com/tarm/goserial"
    "time"
)

func main() {
    // ... (code to open the serial port and write data)

    time.Sleep(time.Second / 2)

    var buf []byte

    for {
        n, err := s.Read(buf)

        if n > 0 {
            break
        }
    }

    fmt.Println(string(buf[:n]))

    // ... (code to close the serial port)
}</code>

<code class="go">package main

import (
    "bufio"
    "fmt"
    "github.com/tarm/goserial"
)

func main() {
    // ... (code to open the serial port and write data)

    // Create a bufio.Reader with a defined delimiter
    reader := bufio.NewReader(s)

    // Continuously read data until the delimiter is encountered
    reply, err := reader.ReadBytes('\x0a')

    // Print the received data
    fmt.Println(string(reply))

    // ... (code to close the serial port)
}</code>
