  * This group of IOCTLs deal with the record settings of the DSP
  *
  * The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
  * Setting a lower depth reduces latency, but increases the demand of the
  * application to service the driver without frame loss.  The DSP has 480
  * bytes of physical buffer memory for the record channel so the true
  * maximum limit is determined by how many frames will fit in the buffer.
  *
  * 1 uncompressed (480 byte) 16-bit linear frame.
  * 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
  * 15 TrueSpeech 8.5 frames.
  * 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
  *
  * The default in the driver is currently set to 2 frames.
  *
  * The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
  * number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
  * signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
  * against over-scaling, if the multiplication factor times the input
  * signal exceeds 16 bits, overflow distortion will occur.  The default
  * setting is 0x100 (1.0).
  *
  * The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on

  * the standard DTMF digits and 28 - 31 are the DTMF tones for A, B, C & D.
  * The positions used internally for Call Progress Tones are as follows:
  *    Dial Tone   - 25
  *    Ring Back   - 26
  *    Busy Signal - 27
  *
  * The freq values are calculated as:
  * freq = cos(2 * PI * frequency / 8000)
  *
  * The most commonly needed values are already calculated and listed in the
  * enum IXJ_TONE_FREQ.  Each tone index can have two frequencies with
  * different gains, if you are only using a single frequency set the unused
  * one to 0.
  *
  * The gain values range from 0 to 15 indicating +6dB to -24dB in 2dB

  * The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
  * Call Progress Tones (CPT).  This is accomplished by setting up an array of
  * IXJ_CADENCE_ELEMENT structures that sequentially define the states of
  * the tone sequence.  The tone_on_time and tone_off time are in
  * 250 microsecond intervals.  A pointer to this array is passed to the
  * driver as the ce element of an IXJ_CADENCE structure.  The elements_used
  * must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
  * termination variable defines what to do at the end of a cadence, the
  * options are to play the cadence once and stop, to repeat the last
  * element of the cadence indefinitely, or to repeat the entire cadence
  * indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
  * structures.  If the freq0 variable is non-zero, the tone table contents
  * for the tone_index are updated to the frequencies and gains defined.  It
  * should be noted that DTMF tones cannot be reassigned, so if DTMF tone
  * table indexes are used in a cadence the frequency and gain variables will
  * be ignored.
  *
  * If the array elements contain frequency parameters the driver will
  * initialize the needed tone table elements and begin playing the tone,
  * there is no preset limit on the number of elements in the cadence.  If
  * there is more than one frequency used in the cadence, sequential elements
  * of different frequencies MUST use different tone table indexes.  Only one
  * cadence can be played at a time.  It is possible to build complex
  * cadences with multiple frequencies using 2 tone table indexes by
  * alternating between them.
