To set APM level:
camcontrol cmd ada0 -a "EF 05 00 00 00 00 00 00 00 00 xx 00"
To disable it:
camcontrol cmd ada0 -a "EF 85 00 00 00 00 00 00 00 00 00 00

To set AAM level:
camcontrol cmd ada0 -a "EF 42 00 00 00 00 00 00 00 00 xx 00"
To disable it:
camcontrol cmd ada0 -a "EF C2 00 00 00 00 00 00 00 00 00 00
