Hangs On When Reading

[Moon-developer]

I tried running this and had to tweak some parts to run with python3, edited the print functions to have braces and to encode certain strings when passing it as an argument, it runs fine and opens a port on COM3 but I seems to just freeze/hang completely when executed. can't even CTRL+C/Z the terminal, needed to close the terminal completely. Any ideas as to why?

Can your share your tweaks please, I am trying to run it with python 3.7 too.
