Could someone give me the identification strings of *Agilent* VNAs.

I'm writing some GPIB software to control my old dinosaurs - an 8720D and 8753A (which I will probably sell as soon as I have fixed the damaged caused by an idiot packing it for transatlantic shipping.)  I'm using C code like this, which works with National Instruments boards. 

*ibrd(device_descriptor, identification_string ,100);*

I'd like to make the code work on as many VNAs as reasonably practical, so I can open-source it and let others use if if they wish. But I don't intend trying it to get to work on every model, especially as I will have no way of testing it. 

The problem is I need to be able to identify the instruments I don't have. I do *not have any Agilent* instruments - *only HP*. The ID string from them is looking like this. 

*HEWLETT PACKARD,8720D,0,7.74*

Could someone give me a sample of what it would look with with an Agilent VNA? Would for example "Agilent" be spelt as "AGILENT" or "Agilent"? 

I'm not going to bother trying to include USB controlled devices like my FieldFox which is on order.
