Modifications that include regex "particle" classes for status responses.
This driver uses the chunker to filter all messages destined for it, so
these mods include the classes that allow the chunker to deliver all
chunks applicable to this driver.  Next is to return the response to
the dump commands (now sent as a result of acquire_status) as a string.
That might involve exposing both dump commands rather that abstracting
them within a single acquire_status command.
