Hi!

I'm having an issue with IIC to Serial UART module.

Issue:

"

pi@raspberrypi:~/DFRobot_IICSerial/python/raspberrypi/examples $ python demo_tx_and_rx.py
Traceback (most recent call last):
File "/home/pi/DFRobot_IICSerial/python/raspberrypi/examples/demo_tx_and_rx.py", line 23, in <module>
from DFRobot_IIC_Serial import *
File "/home/pi/DFRobot_IICSerial/python/raspberrypi/DFRobot_IIC_Serial.py", line 24, in <module>
from serial.serialutil import SerialBase, SerialException, to_bytes, \
ImportError: cannot import name 'portNotOpenError' from 'serial.serialutil' (/usr/local/lib/python3.9/dist-packages/serial/serialutil.py)
"

I have tried to reinstall PySerial with no success. Any advices are welcomed :)
