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