Hi,

I have checked (thanks for the advise) and found that ioperm 0.4.1 is 
installed. I am using cygwin 1.5.15-1 and "gcc" and "make" to build things.

I am logged in with a user that has administrator rights, though not 
as "administrator" itself.

Is there anything that one needs to configure in Windows to help enable 
parallel port access cygwin? Is there a need for "DOS printing support" to be 
turned on or anything.

Thanks
Simon
