make term BOARD=samr21-xpro PORT=/dev/ttyACM1
~~~~~~~~

For flashing and accessing the board via the serial interface, the current user
needs to have the correct access rights on the serial device.
The easiest way to ensure this is to add the current user to the group that is
owning the serial device. For example, this can be achieved on Linux by issuing
the following line, logging out and logging in again:

~~~~~~~~ {.sh}
sudo usermod -aG $(stat --format="%G" /dev/ttyACM0) $USER
~~~~~~~~

Note that the `PORT` macro has a slightly different semantic in `native`. Here
it is used to provide the name of the TAP interface you want to use for the
virtualized networking capabilities of RIOT.
