Hello Uwe,
TD/RD: Flash LED on data transmission (default)
CTS: DCE Ready to accept data from the DTE.
DSR: DCE is ready to receive and send data.
CAR: DCE is receiving a carrier from a remote DTE.
RNG: DCE has detected an incoming ring signal.
The mode can be changed for example with the following command:
echo "CTS" /sys/class/leds/<led>/mode
I wonder if the abstraction is better be done such that you can also
configure the mode to trigger on (for example) TD and RNG. Then you'd
need one property per signal and then something like the following
would
be possible:
p=/sys/class/leds/<led>
echo 1 > $p/tx
echo 0 > $p/rx
echo 1 > $p/rng
I thought about that before implementing this patch set, but then I
discarded it.
Coding several states would then become confusing for someone who look
at the LED.
I have now consciously decided that I want only display one state.
Best regards
Uwe
