When my USB to COM gateway is connected to the PC (I see the COM5 in the Device Manager), this COM port isnt included in the list returned by listports.comports().Instead I only get COM4 which seems to be connected to a modem (I dont see it in the COMLPT section of Device Manager).Start by trying import serial.tools.listports; print(comport.device for comport in serial.tools.listports.comports()).
Only if that doesnt work for you are any of the answers below relevant to you. Instead, it generates a list of object references to ListPortInfo objects. To get the names or other information you must use the attributes of these objects when building the list. ![]() Id simply detect the OS version, then based on that have a switch available for the various cases. Pyserial List Available Ports How To Make AIm just wondering how to make a viable COM port deconnection on windows with python. This is because Linux, at least, lists a boatload of ports as files in dev which arent connected to anything. If youre running in a terminal, devtty is the terminal in which youre working and opening and closing it can goof up your command line, so the glob is designed to not do that. A whole lot more information exists in the list, per the pyserial tools documentation. Ive corrected the list faux pas, not sure how I missed something glaring like that. For example, if you use a list comprehension to demonstrate a simple concept, a novice might get lost in the list comprehension and miss the base concept. If a list comprehension is the best way to do it, show the long hand version first, then how to shorten it. You teach your point and reinforce the list comp at the same time. Then use CreateFile and GetCommConfig with each device name in turn to figure out whether its a serial port. This could be a great answer to a slightly different question, but is out of place here.
