4 Contact: linux-leds@vger.kernel.org
6 Specifies the tty device name of the triggering tty
8 What: /sys/class/leds/<tty_led>/rx
12 Signal reception (rx) of data on the named tty device.
13 If set to 0, the LED will not blink on reception.
14 If set to 1 (default), the LED will blink on reception.
16 What: /sys/class/leds/<tty_led>/tx
20 Signal transmission (tx) of data on the named tty device.
21 If set to 0, the LED will not blink on transmission.
22 If set to 1 (default), the LED will blink on transmission.
24 What: /sys/class/leds/<tty_led>/cts
29 DCE is ready to accept data from the DTE.
30 If the line state is detected, the LED is switched on.
31 If set to 0 (default), the LED will not evaluate CTS.
32 If set to 1, the LED will evaluate CTS.
34 What: /sys/class/leds/<tty_led>/dsr
39 DCE is ready to receive and send data.
40 If the line state is detected, the LED is switched on.
41 If set to 0 (default), the LED will not evaluate DSR.
42 If set to 1, the LED will evaluate DSR.
44 What: /sys/class/leds/<tty_led>/dcd
48 DCD = Data Carrier Detect
49 DTE is receiving a carrier from the DCE.
50 If the line state is detected, the LED is switched on.
51 If set to 0 (default), the LED will not evaluate CAR (DCD).
52 If set to 1, the LED will evaluate CAR (DCD).
54 What: /sys/class/leds/<tty_led>/rng
59 DCE has detected an incoming ring signal on the telephone
60 line. If the line state is detected, the LED is switched on.
61 If set to 0 (default), the LED will not evaluate RNG.
62 If set to 1, the LED will evaluate RNG.
