h2. Modem related:

15 5 Denis 'GNUtoo' Carikli
The modem runs non-free software, which is loaded but not shipped by Replicant.
* When using flight mode, The main CPU has to ask the modem to power itself off.
17 1 Denis 'GNUtoo' Carikli
* The modem is isolated:
** It doesn't use shared memory with the CPU, instead it uses an "HSIC" bus.
19 3 Denis 'GNUtoo' Carikli
** We are not aware of it being able to access the GPS, but it woulnd't be surprising if it still could (by having a direct connection to it).
** It has no access to the other CPU peripherals.
