Re: [PATCHv2 1/4] modem_shm: Add Modem Access Framework

Maybe tty can do this, but want to have all modem related  separately.
There are many such hardware and many drivers coming up in near future.

tty can't do all this. We have similar things with stuff like CAIF. Modem
has gone from pretending to be a serial port (tty) to appearing as a
smart multi-function controller.

tty is the right way to expose any actual 'AT' modem emulation type
stuff, but it's not really relevant for most uses of a modern 3G/4G modem
- also also too slow !
