SerializableMessage

public class SetPower
extends BMPRequest<BMPRequest.BMPResponse>

A request for the BMP to power on or power off some boards. There is no response payload.

Note: There is currently a bug in the BMP that means some boards don't respond to power commands not sent to BMP 0. Because of this, this message should always be sent to BMP 0!

Handled by cmd_power() in bmp_cmd.c, which in turn calls proc_power() in the same file.
