Communication is performed through 17 1.1 nisimura character sequences, whose definition and usage depend on the 18 1.1 nisimura .Tn NAS 19 1.1 nisimura product models. 20 1.1 nisimura .Pp 21 1.1 nisimura The device file 22 1.1 nisimura .Pa /dev/satmgr 23 1.1 nisimura can be written to control the satellite processor and the LEDs. 24 1.1 nisimura Reading it will return single characters for button press events. 25 1.1 nisimura This facility was designed to implement a 26 1.1 nisimura .Tn NAS 27 1.1 nisimura control 28 1.1 nisimura .Tn CGI 29 1.1 nisimura program. 30 1.1 nisimura .Pp 31 1.1 nisimura .Nm 32 1.1 nisimura detects a soft power-off condition, which is triggered by holding 33 1.1 nisimura the front panel power button pressed for several seconds. This 34 1.1 nisimura driver can optionally invoke 35 1.1 nisimura .Xr powerd 8 36 1.1 nisimura to get a finer control over the system shutdown procedure. It is 37 1.1 nisimura capable of reporting a power-button-pressed event. Refer to the 38 1.1 nisimura .Xr powerd 8 39 1.1 nisimura manual section for more details. 40 1.1 nisimura .Pp 41 1.1 nisimura For 42 1.1 nisimura .Tn "Kurobox/Linkstation" 43 1.1 nisimura .Tn NAS 44 1.1 nisimura products it also provides a way to 45 1.1 nisimura toggle the system watchdog with the 46 1.1 nisimura .Xr sysctl 8 47 1.1 nisimura utility.
