Hey,
do I need to do something like:
----
f = filp_open("/dev/ttyS0", O_RDWR | O_NOCTTY | O_NDELAY, 0600);
fs=get_fs();
set_fs(KERNEL_DS);
---
Is there really no API for a uart attached device to communicate with it?
That would be the last thing I thought of :(.
Cheers,
Thilo

Hmm or not :( ... at a first glance it was.But this is for a driver which implements the UART support but I want to use the UART but not implement it's hw support.As a i2c_module doesn't implement the i2c controller support but uses it. Or do I miss something? Cheers, Thilo On 18.08.2014 13:11, Cestonaro Thilo wrote:Thx Greg. This one I missed! But it's what I searched for.

So I was wondering which the best way is to do this. For a i2c device there is the i2c subsystem with it's "module_i2c_driver(foo_driver);" and so on. But I couldn't find any equivalent for a uart device.Did you see include/linux/serial_core.h ?
