If the code gets an error back when it tries to change the voltage then
it should assume that the attempt to change the voltage did not succeed.
Should an attempt to change the voltage not succeed it seems reasonable
to assume that the voltage did not change and is the same as before.
The obvious thing would therefore appear to be for the code to proceed
with that assumption and act accordingly.
