There are a couple. One in particular is for a digi serial port card. Their driver for
it appears to be GPL but part of this app uses it and I need to include one of the header
files and link against it's library. So I guess I can't do that as far as the library goes
but how about the include file? I guess the thing to do would be to contact them and
see what they are willing to do with us.
