As I told you, by making them a R/W variable. Have a look at the  
docs/new-drivers and look for 'dstate_setflags'.

Not recommended. Any variables from the configuration files require  
reloading the driver. It is probably much easier to make this a R/W  
variable, so that you can modify it on the fly via 'upsrw'.

> Actually battery.current.recharge would not be advertised by the driver.

In that case, you can name it as you please, although we certainly  
don't recommend parameters that are hidden.
