Hello,
i want to access serial port (PC, other Linux based hardware) from a kernel module, but without writing a new low level driver. Is this possible ?
Background: We have a device which is connected to the serial port. We can access this device without problems from user space programmes via /dev/ttySx. But now, we want to move the control software into a kernel module. I don't think we can still use open, read, write to /dev/ttySx anymore.
Regards,
Martin
