ampy leaves ports open in Windows about ampy HOT 2 CLOSED

Ah that's a tricky one since the pyboard.py file from MicroPython's source is what owns and controls the serial connection. I try not to modify this file since it's pulled from their repo and might change over time, but it does look like I might be able to ensure the close is called on the serial port even if the program crashes or ctrl-c exits. I just added logic in the latest 1.0.1 version of the tool so it will try to close the serial port no matter what when exiting or crashing. I couldn't repro it to confirm but try upgrading to the latest ampy and let's see if that helps make ctrl-c not keep the port open. You can upgrade by running:

pip install adafruit-ampy --upgrade

Look for the 1.0.1 version to have this change, thanks!

I installed your version 1.0.1, thanks very much for the update. I'm able to work with the high COM port numbers, no problem. However I am still seeing random situations where ampy hangs for some reason and I have to control-c to exit. It is probably 1 out of 5 times. When this happens I am seeing a zombie python process in the windows task manager and I have to manually kill it. I can then invoke the exact same command and it usually works.

There is no obvious pattern to it, even "ampy --port COM24 ls" may fail.
