Hello, I run Win 10 at my laptop...

 

I have installed a virtual serial port (com3), but every time I try to use it, I get the error

"com. port open fail, please check if this port is used by another program"

 

I try to find a solution for a long time, but no luck so far.

 

In proccess tab of task manager, I see only "com surrogate", I close it, but it does not free up the port...

 

Any ideas?

I found the problem.

I must pass settings every time I need it.

 

I thought, that once is enough.
