py-junos-eznc: IO Exception Over Serial On Windows

I cannot get PyEZ to connect to my juniper switch on Windows using the serial port. For my application I cannot use SSH/telnet and I need it to work over the serial port.

On login I get an error in tty_netconf._receive() with the usage of select.

According to the official python docs the select operation is not supported on Windows for file objects (https://docs.python.org/3/library/select.html?highlight=select#select.select).

Is there something else than the select than can be used to wait on the IO under Windows ?

Thanks

Here is the command and the output with the error.

Using Windows 10 1809 Python 3.6.8 junos-eznc 2.2.1

To Replicate

import sys
import logging
import time
from jnpr.junos import Device
from jnpr.junos.utils.config import Config

logging.basicConfig(level=logging.DEBUG)

dev = Device(mode='serial', port='COM4', user='root', passwd=None)
dev.open()

Output
