| |
Hi,
I have a question concerning the line discipline behaviour for serial devices. When the line discipline is set via ioctl from user space to e.g. N_PPP and the userspace program returns without resetting the line discipline back to N_TTY, the serial device cannot be used (ENODV) until an appropriate ioctl (to N_TTY) is performed. Is there any reason for the fact that the line discipline is not reset by the kernel , when closing the device.
Could you please CC me on answers and comments ?
Kind regards,
Christopher Meller
