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.

wandered by www.agilent.com and typed "8665a programming manual"
into the search and found:
http://cp.literature.agilent.com/litweb/pdf/08665-90078.pdf
Chapter 4 covers programming, which appears to use "HP-SL", which is indeed "different" but appears well documented.
have fun
