mos license
mos --port DEVICE_ADDRESS license
Licenses are bound to devices, and they are permanent.
The mos license
command creates a unique license string specific
for a device,
and updates device.license
configuration parameter, which "unlocks"
the device and removes restrictions. The License Manager decreases
the number of available licenses and saves a unique
license string. The next time mos license
is run for the same device,
an old license string is returned by the License Manager
but the number of available licenses is not decreased.
Thus a device, once licensed, is licensed permanently.
