I discovered a driver config file at:

My XML file looks like this:

The values appear to be hexadecimal formatted integers in little endian order. For example, take the ASI461 gain "6400000000000000", and then converting the first two characters from hex to integer: 0x64 = 100
As for (anti) dew heater, I'm guessing it takes values of:
0000000000000000 : off
0100000000000000 : on
