CHANGES FILE

This tarball is ixj-0.1.25.tgz and has the following changes included
since the previous release (ixj-0.1.24.tgz):

*  The ixj driver now has an "official" major number assigned to it.
   The old, dynamic method of loading and unloading the module with a
   load script is now gone.  Please run the new script (ixj_dev_create)
   to ensure you have deleted the old device files from /dev and to
   create the new files with the new assigned major number (159).


*  You should no longer use the "ixj_load" and "ixj_unload" scripts.
   You must, however, run the script

	ixj_dev_create

   once to remove any stray device files left in the /dev directory,
   and to create the new officially designated device files.


*  You can now use insmod to load the actual module. This implies that 
   you should put the module (ixj.o) in a common module directory. 
   We recommend that you copy the driver to 

	/lib/modules/<kernel-rev>/misc

   Our current preferred location is /lib/modules/2.2.9/misc.  You should
   run the command "depmod -a" to allow depmod to rebuild it's dependency
   information tables.

   Using insmod is easy and works in all cases.  You simply type a
   line that looks like this:

	insmod ixj io=0x340,0x350,0x360,0x0370 ixjdebug=0

   This particular line loads the driver and tells it to interface to
   cards found at io addresses 0x340,0x350,0x360,0x0370 (as defined
   and enabled in the isapnp.conf file).  If you have only one card
   in the system, it will look something like this:

	insmod ixj io=0x300 ixjdebug=0

   This will load the driver and enable the card at io address 0x300.


*  If you want to use kerneld to automatically load the driver when you
   need it (with no user action required), you must have compiled your 
   kernel to support kerneld.  You can check for this by looking at 
   /usr/src/linux/.config and you should see this:

	#
	# Loadable module support
	#
	CONFIG_MODULES=y
	# CONFIG_MODVERSIONS is not set
	CONFIG_KMOD=y

   Edit the /etc/conf.modules file and add the following lines:

	options ixj io=0x300 ixjdebug=0
	alias char-major-159 ixj

   Note that if you have multiple cards (see above insmod section) then
   you will need to set the options line appropriately.  For example,
   if you had four cards at io addresses 0x340,0x350,0x360,0x0370 (as defined
   and enabled in the isapnp.conf file) you would use a line like this:

	options ixj io=0x340,0x350,0x360,0x0370 ixjdebug=0
	
   If you do not add the "alias char-major-159 ixj" line then modprobe will
   fail, since it needs this to map the module to the major device number.


*  The ixj driver is not compiled with MODVERSIONS enabled.  What this means 
   for you is that if you have compiled your kernel to support MODVERSIONS 
   then you will get an error when you do a "depmod -a" - this is simply a 
   warning to you that there is a mismatch between the hash-code 
   calculated by the module for it's symbol table, and the one that the
   kernel calculated.  It does not mean the module won't work - only that
   kernel versioning for the driver will not work.  If you want to see if
   you have things right for the present state of MODVERSIONS support,
   look in /usr/src/linux/.config and you should see this line:

	# CONFIG_MODVERSIONS is not set

   We will almost certainly add MODVERSIONS support in the next version,
   which may mean that you all will have to recompile your kernel.  It 
   really is a *Good Thing* in the long run, so plan on the fact that we 
   will eventually use it.


*  The driver ixj.o has the following improvements:

   - fixed a bug that resulted in chopped audio in non-compressed codecs 
     as a result of doing DTMF detection.  It's now fixed.
 
   - added the ability to play tones, including DTMF and call progress
     tones.  Please see the new files:

	playtone.c - shows DTMF examples
 	busytone.c - shows both busy and ringback examples

     These files give examples of how to use the new ioctl calls to 
     accomplish the playing of tones.

  - added support for the new official major number.
