This is a good case for centralized exception processing.  I did not
know what was involved in programming exceptions for the synthesizers.

The direct synth mode is a separate issue, and yes, it should be easy to
implement.  It isjust a matter of adding a few lines to each of the
drivers.  I personally have been working on some other projects, but I
can get to that soon.

Here is my personal point of confusion about how punctuation levels
operate.

Speakup has punctuation levels and so do synths.  The ltlk family for
example have 16 punctuation levels to speakup's 3.  Both levels can
be set.  I guess the punc_level sys file sets the speakup punctuation
level and the ltlk/punct sys file sets the ltlk punctuation level.
When do we use the synth punctuation level?  Which level is controlled
by the keyboard?
