221* return with a positive indication on the exception set.  The dtmf_ready
222* bit indicates if there is data waiting in the DTMF buffer.  The
223* hookstate bit is set if there is a change in hookstate status, it does not
224* indicate the current state of the hookswitch.  The pstn_ring bit
225* indicates that the DAA on a LineJACK card has detected ring voltage on
226* the PSTN port.  The caller_id bit indicates that caller_id data has been
227* received and is available.  The pstn_wink bit indicates that the DAA on
228* the LineJACK has received a wink from the telco switch.  The f0, f1, f2
229* and f3 bits indicate that the filter has been triggered by detecting the
230* frequency programmed into that filter.
