serial port in use

[curious]

I want to upload the new update of rflink.
I want to use the RF Linkloader but the loader only sees one port (Com1) and when I want to use that port rfloader reports it is allreadyin use

I rebooted the raspberry sevral times but nothing changes. When restarting raspberry the usb hub is detected.

How to solve this ?

rflink loader kis a windows pc tool.. you can not run it on the Pi

I realized that this morning, feel rather stupid. Was to eager to upload the new firmware.

But this gives me the opportunity to thank the stuntteam for adding my doorbell

Works great.

And continued discovering all possibilities ....
