[avrdude-dev] help - win2k:ppi (dt006) issues with avrdude, uisp works fine

[Davin Gibb]

Hi guys, I'm hoping someone will be able to shed some light on this one!

I have a dt006 parallel port programmer. I'm using Win2K. All my software 
has come from AVR GCC at avrfreaks.net (so I'm using the cygwin compiled 
avrdude-4.2.0).

My parallel port under windows is called 'lpt1', however, I'm on a laptop, 
so the base address is 0x3bc.

uisp works a treat, avrdude (and ponyprog) are no good, below is the 
output (first success with uisp, then fail with avrdude, yes I have 
getio.sys loaded). 

You guys have any clue as to why they are different? Any help greatly 
appreciated.

Thanks in advance, Davin.
