When I try to open /dev/ttyUSB0 with serial-term, following error shows:

Opening serial port: Permission denied, /dev/ttyUSB0

I know I can add my user to a group that has access to /dev/tty*. Probably something like:

# sudo usermod -aG tty $(whoami)

However, Is there anyway to access /dev/ttyUSB0 within emacs (just put my password, whenever I access to serial ports). Perhaps something like run M-x serial-term with root privileges?
