This is actually fine, but please re-flow the text to take advantage of
the available space.  There's no reason to stick with 50 character
maximum now.

I agree, the standard says that all strings should be in quotes.  If
some modem does not follow this standard then we will need to quirk it
specifically.  For now I think this is fine.

Please fix up the other style issues commented on by Yang and resubmit
