OTOH, why do you want to do the serial stuff in kernel land? Isn't it
a *lot* easier to do it in userspace? What's your specific device you
want to work on?
You didn't actually answer any of my questions.
sorry.
I want to use the interface aka /dev/ttyS0.
I want to process data inside of a kernel module to provide it /proc
(done) or as own char-dev (done).
but I can not grab the data.
It is part of my project in my studies.
It is more a conceptual work, but important. I want to release a howto,
when I complete.
You still answer unasked questions. Please answer inline:
* Why do you wanto to do the serial stuff in kernel land?
It is more a conceptual work, but important. I want to release a howto,
when I complete.
* Isn't it easier to do it in userspace?
yes
* What specific device do you work on?
I want to use the interface aka /dev/ttyS0. (text-stream)
* New: Is it a wise idea to do it in kernel land?
no, explicitly not. To get known hwo to deal with data from devices.
The /proc filesystem has been somewhat obsoleted in favour of sysfs
for device/driver information.
