Hi
I'm trying to use PySerial and I'm getting 'Access Denied'. I don't know if this is a bug from PySerial library or I'm doing something totally stupid :-)

Implement a serial port read loop and dispatch to a Protocol instance (like the asyncio.Protocol) but do it with threads. Calls to close will close the serial port but it is also possible to just stop this thread and continue to use the serial port instance otherwise. init (serialinstance, protocolfactory) ¶. Feb 07, 2006 I need to access the serial port via python on a windows machine. Reading on the web, there are three solutions: pyserial, siomodule and USPP. Pyserial seems.
Python Serial Port Example
Error that I'm getting is:
Python code to read the serial port of a Raspberry Pi. Example to debug MySensors gateway messages. Python code to read from the serial port of a Raspberry Pi. 16 November 2016 1. Save Saved Removed 0. To develop your projects with Arduino or ESP8266 on Raspberry Pi basis, one may need to access the serial port for the update. This tutorial. Step 2: Test with Python and a terminal emulator. You will now need to edit files /etc/inittab and /boot/cmdline.txt as described at RPiSerialConnection#PreventingLinuxusingtheserialport.When you have done this - remember to reboot after editing - the terminal emulator set up in Step 1 will no longer show any output from Linux - it is now free for use by programs. Python Serial Port Extension. Python Serial Port Extension for Win32, OSX, Linux, BSD, Jython, IronPython.
I checked the port with Portmon while I was running that script to make sure that the port gets closed and it is.
So somehow try and except to open the already opened port messed up the object. I also tried to destroy the object and create it again and I got the same error.
Does any know if this is a bug or am I doing something wrong.
Thanks
