When I try to to open a COM port in Docklight, I receive an error message “The communication port COMxxx could not be opened. Windows Error #5 – Access is denied” or simular. I carefully checked that no other application is using this COM port. I also noticed the error only appears sometimes, or using a certain Docklight version. The Windows Hyperterminal software seems to be fine, for example.
