Writing to ports using C

[Carl Parrish]

Not that I'm complaning, because I really don't think the list cares all
that much. But wouldn't this be a perfect thread for plug-devel. Here
are the reasons I think. 

1) Just on the off chance that some programmer only subscribe to
plug-devel
2) For the people (like me) who would check plug-devel more often
3) So that non programmer wouldn't have to delete (I don't think too
many on our list would mind but still)
4)So that anyone searching the plug-devel archives wouldn't think it was
dead (or *did* we kill it?).
