Actually, not that different.  HP-SL was the original name for SCPI when we initially developed it for HP internal use.  We renamed it TM-SL and gave it to the industry.  They immediately renamed it SCPI and then made some minor changes before adopting.  A dozen or so instruments made it out under the HP-SL moniker.

I second the panel driver approach.  If you open the 8665 driver here:
http://www.home.agilent.com/upload/cmc_upload/All/hp8665a.id

And search down about 20% of the way, you will find the following component:

COMPONENT RF_OFF_ON;
    TYPE DISCRETE;
    VALUES OFF,ON;
    INITIAL OFF;
    SET ACTIONS;
        SELECT RF_OFF_ON;
        CASE OFF;
            OUTPUT STRING "POWER:STATE OFF";
        CASE ELSE;
            OUTPUT STRING "POWER:STATE ON";
        END SELECT;
    END ACTIONS;
    GET ACTIONS;
        OUTPUT STRING "POWER:STATE?";
        ENTER XSTRING FORMAT "K";
        SELECT XSTRING;
        CASE "0";
            FETCH (RF_OFF_ON)OFF;
        CASE ELSE;
            FETCH (RF_OFF_ON)ON;
        END SELECT;
        STORE RF_OFF_ON;
    END ACTIONS;
END COMPONENT;

Panel drivers were written in a funky FORTH dialect, but the command strings are pretty obvious.
