  75*
  76* This group of IOCTLs deal with the record settings of the DSP
  77*
  78* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
  79* Setting a lower depth reduces latency, but increases the demand of the
  80* application to service the driver without frame loss.  The DSP has 480
  81* bytes of physical buffer memory for the record channel so the true
  82* maximum limit is determined by how many frames will fit in the buffer.
  83*
  84* 1 uncompressed (480 byte) 16-bit linear frame.
  85* 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
  86* 15 TrueSpeech 8.5 frames.
  87* 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
  88*
  89* The default in the driver is currently set to 2 frames.
  90*
  91* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
  92* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
  93* signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
  94* against over-scaling, if the multiplication factor times the input
  95* signal exceeds 16 bits, overflow distortion will occur.  The default
  96* setting is 0x100 (1.0).
  97*
  98* The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
  99* the most recently recorded frame as a 16 bit value.

 147* This IOCTL allows you to reassign values in the tone index table.  The
 148* tone table has 32 entries (0 - 31), but the driver only allows entries
 149* 13 - 27 to be modified, entry 0 is reserved for silence and 1 - 12 are
 150* the standard DTMF digits and 28 - 31 are the DTMF tones for A, B, C & D.
 151* The positions used internally for Call Progress Tones are as follows:
 152*    Dial Tone   - 25
 153*    Ring Back   - 26
 154*    Busy Signal - 27
 155*
 156* The freq values are calculated as:
 157* freq = cos(2 * PI * frequency / 8000)
 158*
 159* The most commonly needed values are already calculated and listed in the
 160* enum IXJ_TONE_FREQ.  Each tone index can have two frequencies with
 161* different gains, if you are only using a single frequency set the unused
 162* one to 0.
 163*
 164* The gain values range from 0 to 15 indicating +6dB to -24dB in 2dB
 165* increments.

 303*
 304* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
 305* Call Progress Tones (CPT).  This is accomplished by setting up an array of
 306* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
 307* the tone sequence.  The tone_on_time and tone_off time are in
 308* 250 microsecond intervals.  A pointer to this array is passed to the
 309* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
 310* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
 311* termination variable defines what to do at the end of a cadence, the
 312* options are to play the cadence once and stop, to repeat the last
 313* element of the cadence indefinitely, or to repeat the entire cadence
 314* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
 315* structures.  If the freq0 variable is non-zero, the tone table contents
 316* for the tone_index are updated to the frequencies and gains defined.  It
 317* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
 318* table indexes are used in a cadence the frequency and gain variables will
 319* be ignored.
 320*
 321* If the array elements contain frequency parameters the driver will
 322* initialize the needed tone table elements and begin playing the tone,
 323* there is no preset limit on the number of elements in the cadence.  If
 324* there is more than one frequency used in the cadence, sequential elements
 325* of different frequencies MUST use different tone table indexes.  Only one
 326* cadence can be played at a time.  It is possible to build complex
 327* cadences with multiple frequencies using 2 tone table indexes by
 328* alternating between them.

 696* The intercom IOCTL's short the output from one card to the input of the
 697* other and vice versa (actually done in the DSP read function).  It is only
 698* necessary to execute the IOCTL on one card, but it is necessary to have
 699* both devices open to be able to detect hook switch changes.  The record
 700* codec and rate of each card must match the playback codec and rate of
 701* the other card for this to work properly.
