Pyserial works. I've been using it almost daily for many
years. Either your program is broken, your serial port is
broken, or the device connected to the serial port is broken.

Ah yes, the problem is in line 89 of your program.
We've no way to help if you don't provide details. If you
really want help, write as small a program as possible that
exhibits the problem. I'd like to emphasize _small_. The
larger the program the less likely people are to look at it,
and the less likely they are to find the problem if they do
look at it.
Much of the time the exercise of writing a small demo program
will lead you to the answer. If not, then post it, along with
the output from the program that shows the problem.
Then we can tell you what you did wrong.
