I don't know the 'right' way to do HwrPluggedIn now. We have this thing
called a HAL (Hardware Abstraction Layer) and I know there's some stuff in
the HAL to support this, but I think the HAL routines are considered
private, so you shouldn't use them any more than you used to use
HwrPluggedIn.
I'm pretty sure there is a 'soft' character you can enqueue to change the
backlight. vBacklightChr sounds right to me. (I say 'soft' because it
does not correspond to a physical key, instead it's psuedo-generated on
some platforms by holding down the power switch for a while. Note that
holding down the power switch for a while will not necessarily enqueu a
vBacklightChr on all devices, nor will all devices necessarily respond to
enqueing a vBacklightChr by toggling the backlight!)
So the 'right' answer here is don't use this routines, because you don't
need them. Let the OS handle that stuff instead. (yes, yes, I can hear
the chorus already)
