You'll be able to submit all commands via SMS/text command as well, you just need to use the new syntax.

I've implemented my specific features as config vars now, as they give much more freedom. I think it's good to map at least the old standard parameters and
features to their respective new config variables, i.e. PARAM 5 <=> config modem apn, so clients can continue using these, but that should be sufficient for
compatibility.

I think deriving the car_chargestate string from the charge flags is not correct. We've currently got…

    OvmsMetricString* ms_v_charge_state;      // charging, topoff, done, preparing, heating, stopped
    OvmsMetricString* ms_v_charge_mode;       // standard, range, performance, storage
    OvmsMetricString* ms_v_charge_substate;   // tba...

…but no longer their numerical equivalences as metrics -- assuming they are no longer necessary. Are they? I.e. do we need the numerical values other than for
the old V2 protocol?

I'd else translate the old codes to their old numerical values just for the "S" msg.
