Until now, the LED blinks when data is sent via the tty (rx/tx). This is not configurable. This change adds the possibility to make the indication for the direction of the transmitted data independently controllable via the new rx and tx sysfs entries. - rx: Signal reception (rx) of data on the named tty device. If set to 0, the LED will not blink on reception. If set to 1 (default), the LED will blink on reception. - tx: Signal transmission (tx) of data on the named tty device. If set to 0, the LED will not blink on transmission. If set to 1 (default), the LED will blink on transmission. This new sysfs entry are on by default. Thus the trigger behaves as before this change.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
