E4418B RF Pwr Meter firmware update problem

So my "new guys" fried two of my old power sensors... Company purchased Agilent N8481A Pwr Sensors($1200 ea), which should work with our power meter E4418B. I need to update my firmware to latest version for them to work, already upgraded the DSP board ($523), so here is the problem-

Even though the E4418B has an RS-232 (we don't use GPIB at all) connector on back; there is no menu selection to choose it over GPIB, even though the manual says there is. I don't want to spend more on a GPIB PCI board and cable just for a simple firmware update.

Firmware installed is A1.03.00 and I need the latest one A1.09.01

The manual says under menus = System/Input -> Remote Interface -> Select Interface, should let me choose between HPIB or Serial. My E4418B instead of displaying Remote Interface shows HPIB.

Any ideas or help would be appreciated
