avrdude: AVR device not responding

Hi there,

Just getting started with my first project. Im using a serial ISP
programmer to program an ATMega162, and Im having trouble using
avrdude to do, well, anything! avrdude reports:

---------------------------------------------------------------------------------------------------
C:\Utils\WinAVR\bin>avrdude -p m162 -P COM1 -c ponyser -U lfuse:r:-:h -
U hfuse:r
:-:h

avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


avrdude done.  Thank you.
---------------------------------------------------------------------------------------------------

However, when I upload hex files using avrprog from AVR Studio, it
works sweet as! Anyone have any idea what Im doing wrong in avrdude?
Id like to use it, as the tutorials Im working from use it, and
avrprog doesnt seem to be able to set fuse bits (plus avrdude is
runnable from within my IDE :P)

Thanks.
