"TypeError: ord() expected string of length 1, but int found" in network.py

Hi, I'm having an issue getting semonitor.py to run.

I'm running semonitor.py on Arch Linux with the latest updates:

Linux stripe 5.18.7-1-danctnix #1 SMP PREEMPT_DYNAMIC Mon Jul 11 04:43:57 UTC 2022 aarch64 GNU/Linux

I have given the host a fixed ip and there are no services using port 53:

6: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:e0:4c:36:02:b7 brd ff:ff:ff:ff:ff:ff
    inet 192.168.100.1/24 brd 192.168.100.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever

Running Python 3.10.5.

I run the script with sudo python semonitor.py -vv -t n -n eth0.

The output (with redacted MAC) is

TypeError: ord() expected string of length 1, but int found

I started tinkering with it, by removing the ord(), as I read that it is a python2 leftover, but I don't know enough about python to fix the whole script so I stopped after a few hurdles. I read this project was adjusted for python3 so I don't know what is wrong.
