I an testing some software after not sing the IDE for a few days. I now get the error message:
"avrdude: ser_open(): can't open device "\.\COM9": Access is denied."
when I try to upload and the monitor is "open". I could have sworn V2.1.0 had a feature to disable the monitor automatically for upload. Was I dreaming?
I had been using a SAMD21 "M0" board and now I'm using a pro mini with an FTDI Programmer.
UPDATE:
The disable works with the SAMD21 but not the Pro mini
