Topic: Serial port 'COM19' already in use (Read 9 times) previous topic - next topic


The other listed one is Com4, which also didn't work.


Hi all,

I've printed the output to the black screen. Hope someone can help.

Just to update on my effort in finding a solution.  I did quite a fair bit of searching on the web.  Landed on some sites advising to use FTClean.  Did that and reinstall the drivers like the first time.  Select the port and loaded the program.  The same message on Serial port already in use appeared.

I'm really lost.

Please, if anyone could, help me on this. Getting desparate to get it back up.

Why does your error message say you are using COM5?


Hi Digger450,

I don't exactly know what you mean by "using COM5" but when I click upload, it said COM5 already in use and to close off porgrams using it.

I checked in device manager -> Ports -> USB Serial Ports (COM5) -> Port Setting -> Advance.  All ports that I tried are not in used.
