CHANGES FILEThis tarball is ixj-0.1.30.tgz and has the following changes includedsince the previous release:- the ixj.o driver has the following improvements:  - Internet LineJACK POTS port support.  The LineJACK PSTN support    is not implemented yet.  However, the LineJACK will now do    everything that the PhoneJACK will do.  - added the ability to set the buffer "depth" for reads and writes    to the codecs.  The default depth of buffers is 2 frames, but this    can be changed via the IXJCTL_REC_DEPTH ioctl.  From the ixjuser.h file:* 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.    Setting the depth to 1 frame significantly reduces the latency when    using a compressed codec.  - the DSP is properly shut down and idled upon a device close.  Previously,    failure to idle the DSP would result in system lockups in some scenarios.  - hook switch detection now works properly when tones are being played.- the IXJ-HOWTO file has been updated to reflect the new way to load and  unload the driver- the FAQ file was overhauled and updated to add some of the key issues that  have come up in recent weeks.
