I can't argue there. :)

Looks like you run install-filter.exe -i to install and 
install-filter.exe -u to uninstall. However, I had to read their 
installer source code to figure this out, as install-filter.exe doesn't 
seem to provide any command line help. I'm not sure what files it 
requires...

It's rather confusing to explain to most users, though. :) I suspect the 
majority of users will probably have the manufacturer provided Windows 
drivers installed, so the filter is probably best for most. 
Unfortunately, as I've mentioned several times before, the filter seems 
to have some rather serious problems. (The driver could have these as 
well; I've never tested it.)

The API, where provided. However, many displays don't provide this, so 
we'd have to do virtual serial stuff there.
