Hex to ASCII converter for PXE option 43?

Does anyone know of a hex to ASCII converter that can handle PXE client 
option 43s as input? The ones I've found on line so far all try to do a 
character-by-character conversion of the string, which fails.

Alternatively, does anyone have a good reference for how to build the 
option 43, so that I can reverse engineer it?

What I want to do is take some existing DHCP data and convert option 
60/43 pairs into proper vendor profiles. I can do that in my sleep for 
WAPs, phones, etc., but this PXE stuff is giving me a headache. :-/
