Hi All.
I am sorry upfront if this might seem like a stupid question.
I am wanting to have some insight on how a modem plugs into the
linux-kernel at architecture level.
First a bit of history.
I have prior experience of using an onboard-modem on a ubuntu, via
support from modem-manager. There,

Hi All.
We have deployed a simple C-application on an embedded-platform
running Linux, and we spuriously observe file-corruption. In
particular, there is an all-important "config" file, and some of its
lines are lost spuriously.
Now, our application opens quite a few files on the file-systems,

We are using Sierra's USB-to-WWAN driver on Ubuntu-14 for Sierra's
MC8090 modem, and we have a requirement wherein we need to have access
to the modem-serial-port (from our user-application that is).
Right now, we see that /usr/sbin/ModemManager is always connected to

Hi all.
Does there exist a API already to read the file-allocation-table
data-structure on a FAT(8,16,32) file-system?
Having it either in "user", or "kernel" mode will be fine.
If not, does there exist some documentation on how one can do that?
Will be grateful for any pointers :)
