+*
+* 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 most recently recorded frame as a 16 bit value.

+* This IOCTL allows you to reassign values in the tone index table. The
+* tone table has 32 entries (0 - 31), but the driver only allows entries
+* 13 - 27 to be modified, entry 0 is reserved for silence and 1 - 12 are
+* 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
+* increments.

+/******************************************************************************
+*
+* 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 indefinatly, or to repeat the entire cadence
+* indefinatly. 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 indexs 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.
