The port is not being closed

Code:

package main

import (
	"fmt"

	"github.com/goburrow/serial"
	modbus "github.com/things-go/go-modbus"
)

func main() {
	p := modbus.NewRTUClientProvider(modbus.WithEnableLogger(),
	modbus.WithSerialConfig(serial.Config{
		Address:  "\\\\.\\com31",
		BaudRate: 38400,
		DataBits: 8,
		StopBits: 1,
		Parity:   "N",
		Timeout:  modbus.SerialDefaultTimeout,
	}))

	client := modbus.NewClient(p)
	err := client.Connect()
	if err != nil {
		fmt.Println("connect failed, ", err)
		return
	}

	_, err = client.ReadInputRegisters(0x16, 69, 13)
	if err != nil {
		fmt.Println(err.Error())
	}

	fmt.Println("Close err:", client.Close())

	_, err = client.ReadInputRegisters(0x16, 69, 13)
	if err != nil {
		fmt.Println(err.Error())
	}
}

Out:

After the client.Close() the port remains open and continues to work
