This driver allows read the software reset switch state and control the status LEDs. The GPIO pins have their direction (input/output) locked down to prevent possible short circuits. Note that most people get a reset button that is a hardware reset. The software reset button is available on boards from Netgate. Sponsored by: Rubicon Communications (Netgate)

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
provides a simple interface to read the reset switch state and control the
|
|
status LEDs.
|
|
.Pp
|
|
The software controlled reset switch is known to be available on boards from
|
|
Netgate.
|
|
Most people get a button that is a hardware reset.
|
|
.Pp
|
|
All the GPIO pins are locked in their intended setup to disallow any harmful
|
|
settings (the ones that can cause short circuits).
