It looks like your mail client wrapped long lines; you'll want to
resend with a "preformatted" option or something, or use "git send-
email" to make sure the formatting doesn't get screwed up.

Also, are you at all able to give hints in the comments about what kind
of ports these are? AT? GPS? PPP? etc?  That's usually described in the
driver documentation or in the Windows drivers themselves.
