Notes on using the Arduino IDE:
To allow serial port locking, add your user to the dialer group:
pw groupmod dialer -m myuser
(..)"
Did you add your user to the dialer group? That would allow to you to
access modem/vcom devices which seems exactly what you need. The modem
device is /dev/cuaU* for USB-Virtual-COM-Ports :-)

How about /dev/cuaU* ?

Either try adding your user to the dialer group as instructed by the
post-install package message (this is the preferred method, note you
need to logout and login after that), or add `add path 'cuaU*' mode
0660 group operator` as another rule in /etc/devfs.rules so you will
gain access to the /dev/cuaU* files as needed if that method works for
you with other devices :-)
You can restart devfs with `service devfs restart` as root no need to reboot :-)

MINICOM can talk to the /dev/cuaU0 and other serial ports like this so
you can test if communication works with your device if other software
fails :-)
Good luck and have fun! :-)
