Details:

sometimes "something" causes the parallel port to be left in a state where
the reset pin or data pins are driven high by the
STK200 programmer

In this state there is no way to reset the port using avrdude
as the -E parameter is being ignored.

This seems like an oversight, for although the STK200 by design cannot power
the target AVR it can interfere with its operation.

it seems there is a "setpin" where there should be "setmany"

here's a patch :)
==== BEGIN

==== END

IMO havinf setpin and setmany able to me interchanged
without generating a compiler diagnostic is a mistake.
