4.5.5.14. Set Battery Charge Levels
ID 43
FORMAT struct {
unsigned char chargeStart;
unsigned char chargeStop;
} setBattCharge;
DESCRIPTION
This frame requests a remote to change the battery charge management parameters.
The device will answer with a General acknowledge frame. An A720 will not issue
such a frame, but it will answer to it.
chargeStart is the value where the external power (normally a solar panel)
will be enabled to charge the battery;
chargeStop is the value where the external power will be switched off.
From the above two values, the system will compute all other limits (e.g. misery, bat-
tery low, etc.).

The device will answer with a General acknowledge frame. An A720 will not issue
such a frame, but will answer to it.
Note: The format and description of this frame must be detailed later; it is not yet implemented.

DESCRIPTION
This frame is sent as an acknowledge to various Set type of frames. The result field
is NULL if the request was successfully performed; in case of failure, this field may
contain information on the cause of the failure. Its value will depend from the type
