Merge pull request #14 from darrenpearson/master

Minor bug fixes and ldoc updates.  Improved processing of partial messages on ser3B.
Removed bash specific code in opkg-build
Remove the duplicated REG_IOSTATUS define.  It exists elsewhere as REG_IO_STATUS which seems like an altogether better name.
Rework the alpha entry code so that it is table based rather than a big pile of nested if statements.
Not only should this run fast and be smaller but it is much easier to change if ever required.
Clean up the delay code so that it doesn't create an extra instance variable and method.
