S-record type S9, indicating it is a termination record. 
This does not appear to be the case, I had 0xee in my lfuse register.
I have captured the output from avrdude. The Intel format output is a block
containing a single byte, value 0xee. The Motorola format output contains no
data

C:\>avrdude -pm8 -Pcom2 -cstk500 -mlfuse -fi -o-

avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e9307
avrdude: reading lfuse memory:
     0
avrdude: writing output file "-"
:01000000EE11
:00000001FF

avrdude done.  Thank you.


C:\>avrdude -pm8 -Pcom2 -cstk500 -mlfuse -fs -o-

avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e9307

avrdude: writing output file "-"

avrdude done.  Thank you.
