|
.Cd "satmgr0 at eumb? unit 1"
|
|
.Sh DESCRIPTION
|
|
This driver provides an interface to the
|
|
.Tn NAS
|
|
builtin satellite microprocessor which controls the power, front
|
|
panel LEDs, and push buttons.
|
|
Communication is performed through character sequences, whose
|
|
definition and usage depend on the
|
|
.Tn NAS
|
|
product models.
|
|
.Pp
|
|
The device file
|
|
.Pa /dev/satmgr
|
|
can be written to control the satellite processor and the LEDs.
|
|
Reading it will return single characters for button press events.
|
|
This facility was designed to implement a
|
|
.Tn NAS
|
|
control
|
|
.Tn CGI
|
|
program.
|
|
.Pp
|
|
.Nm
|
|
detects a soft power-off condition, which is triggered by holding
|
|
the front panel power button pressed for several seconds.
|
|
This driver can optionally invoke
|
|
.Xr powerd 8
|
|
to get a finer control over the system shutdown procedure.
|
|
It is capable of reporting a power-button-pressed event.
|
|
Refer to the
|
|
.Xr powerd 8
|
|
manual section for more details.
