Um...Good to know. I didn't know that a serial master-slave configuration is worth a number.

@DLMousey I use that pretty frequently.

Something you need to quickly learn about Google:
Looking for things that contain a caret? Drop the caret symbol!
Looking for arguments that start with a hyphen? Drop the leading hyphen!
Looking for a number between two ranges? Don't use Google because while searching 10000..20000 works fine, they quickly annoy the heck out of you by asking if you are a robot every time you search.

@xsacha doesn't using a hyphen force it to look for everything that isn't it?

@SpencerBeige Exactly. Worst thing is searching for -some-args and none of the search results contain it. Then remembering you have to search some-args for them to all pop up.
