FUNCTION: searchStations
==============================================================*/
/**
* Initiates basic seek and scan operations.
* <p>
* This command is used to invoke a basic seek/scan of the FM
* radio band.
* <p>
* <ul>
* This API is used to:
* <li> Invoke basic seek operations ({@link
* #FM_RX_SRCH_MODE_SEEK})
* <li> Invoke basic scan operations ({@link
* #FM_RX_SRCH_MODE_SCAN})
* </ul>
* <p>
* The most basic operation performed by this function
* is a {@link #FM_RX_SRCH_MODE_SEEK} command. The seek
* process is handled incrementing or decrementing the
* frequency in pre-defined channel steps (defined by the
* channel spacing) and measuring the resulting signal level.
* Once a station is successfully tuned and found to meet or
* exceed this signal level, the seek operation will be
* completed and a FmRxEvSearchComplete event will be returned
* to the client. If no stations are found to match the search
* criteria, the frequency will be returned to the originally
* tuned station.
* <p>
* Since seek always results in a frequency being tuned, each
* seek operation will also return a single
* FmRxEvRadioTuneStatus event to the client/application
* layer.
* <p>
* Much like {@link #FM_RX_SRCH_MODE_SEEK}, a {@link
* #FM_RX_SRCH_MODE_SCAN} command can be likened to many back
* to back seeks with a dwell period after each successful
* seek. Once issued, a scan will either increment or
* decrement frequencies by the defined channel spacing until
* a station is found to meet or exceed the set search
* threshold. Once this station is found, and is successfully
* tuned, an FmRxEvRadioTuneStatus event will be returned to
* the client and the station will remain tuned for the
* specific period of time indicated by argument dwellPeriod.
* After that time expires, an FmRxEvSearchInProgress event
* will be sent to the client and a new search will begin for
* the next station that meets the search threshold. After
* scanning the entire band, or after a cancel search has been
* initiated by the client, an FmRxEvRadioTuneStatus event
* will be sent to the client. Similar to a seek command, each
* scan will result in at least one station being tuned, even
* if this is the starting frequency.
* <p>
* Each time the driver initiates a search (seek or scan) the client
* will be notified via an FmRxEvSearchInProgress event.
* Similarly, each time a search completes, the client will be notified via an
* FmRxEvRadioTuneStatus event.
* <p>
* Once issuing a search command, several commands from the client
* may be disallowed until the search is completed or cancelled.
* <p>
* The search can be canceled at any time by using API
* cancelSearch (). Once cancelled, each search will tune to the
* last tuned station and generate both FmRxEvSearchComplete and
* FmRxEvRadioTuneStatus events.

/**
* Initiates RDS based seek and scan operations.
*
* <p>
* This command allows the client to issue seeks and scans similar
* to commands found in basic searchStations(mode, scanTime,
* direction). However, each command has an additional RDS/RBDS
* component which must be satisfied before a station is
* successfully tuned. Please see searchStations(mode,
* scanTime, direction) for an understanding of how seeks and
* scans work.
*
* <p>
* <ul>
* This API is used to search stations using RDS:
* <li> Invokes seek based on program type ({@link
* #FM_RX_SRCHRDS_MODE_SEEK_PTY})
* <li> Invokes scan based on program type with specified dwell period
* ({@link #FM_RX_SRCHRDS_MODE_SCAN_PTY})
* <li> Invokes seek based on program identification ({@link
* #FM_RX_SRCHRDS_MODE_SEEK_PI})
* <li> Invokes seek for alternate frequency ({@link
* #FM_RX_SRCHRDS_MODE_SEEK_AF})
* </ul>
*
* <p>
* Much like {@link #FM_RX_SRCH_MODE_SEEK} in searchStations,
* {@link #FM_RX_SRCHRDS_MODE_SEEK_PTY} allows the client to
* seek to stations which are broadcasting RDS/RBDS groups
* with a particular Program Type that matches the supplied
* Program Type (PTY). The behavior and events generated for a
* {@link #FM_RX_SRCHRDS_MODE_SEEK_PTY} are very similar to
* that of {@link #FM_RX_SRCH_MODE_SEEK}, however only
* stations meeting the set search signal threshold and are
* also broadcasting the specified RDS Program Type (PTY) will
* be tuned. If no matching stations can be found, the
* original station will be re-tuned.
*
* <p>
* Just as {@link #FM_RX_SRCHRDS_MODE_SEEK_PTY}'s
* functionality matches {@link #FM_RX_SRCH_MODE_SEEK}, so
* does {@link #FM_RX_SRCHRDS_MODE_SCAN_PTY} match {@link
* #FM_RX_SRCH_MODE_SCAN}. The one of the differences between
* the two is that only stations meeting the set search
* threshold and are also broadcasting a RDS Program Type
* (PTY) matching tucRdsSrchPty are found and tuned. If no
* station is found to have the PTY as specified by argument
* "pty", then the original station will be re-tuned.
*
* <p> {@link #FM_RX_SRCHRDS_MODE_SEEK_PI} is used the same
* way as {@link #FM_RX_SRCHRDS_MODE_SEEK_PTY}, but only
* stations which meet the set search threshold and are also
* broadcasting the Program Identification matching the
* argument "pi" are tuned.
*
* <p>
* Lastly, {@link #FM_RX_SRCHRDS_MODE_SEEK_AF} functionality
* differs slightly compared to the other commands in this
* function. This command only seeks to stations which are
* known ahead of time to be Alternative Frequencies for the
* currently tune station. If no alternate frequencies are
* known, or if the Alternative Frequencies have weaker signal
* strength than the original frequency, the original
* frequency will be re-tuned.
*
* <p>
* Each time the driver initiates an RDS-based search, the client will be
* notified via a FmRxEvSearchInProgress event. Similarly, each
* time an RDS-based search completes, the client will be notified via a
* FmRxEvSearchComplete event.
*
* <p>
* Once issuing a search command, several commands from the client may be
* disallowed until the search is completed or canceled.
*
* <p>
* The search can be canceled at any time by using API
* cancelSearch (). Once canceled, each search will tune to the

* FmRxEvSearchComplete and FmRxEvRadioTuneStatus events.

* Additionally, this function also allows the client to enable or
