串行端口在macOS上的golang中使用tarm / serial接收数据问题

I successfully write Byte array to port but failed to read from it. function "read" return "read /dev/tty.usbserial1: interrupted system call" error, I running it on macOS sierra 10.12.6, use "github.com/tarm/serial", anyone met the same problem? here is the code:

func TestTarmSerialDataRecvAndSend(t *testing.T) {
    c := &serial.Config{
        Name: "/dev/cu.usbserial1",
        Baud: 9600,
    }

    s, err := serial.OpenPort(c)
    if err != nil {
        fmt.Println(err)
        return
    }

    for i := 0; i < 10; i++ {
        n, err := s.Write([]byte("test"))
        if err != nil {
            fmt.Println(err)
            return
        }

        fmt.Printf("send byte : %v", n)
    }

    fmt.Println("send over")

    buf := make([]byte, 128)
    n, err := s.Read(buf)
    if err != nil {
        fmt.Println(err)
        return
    }

    fmt.Printf("%q", buf[:n])
}
