rxtx-2.1 and rxtx-2.0 changes are kept in the same file.  skip to the version
you downloaded.

2.2 ???

		Fixed the gnu.io.rxtx.properties code that didn't work. 
		Fixed unsafe code in the registerSpecifiedPorts method. 
		Adrian Crum <adrian.crum@yahoo.com>

		Deamon Monitor thread.
		http://mailman.qbang.org/pipermail/rxtx/2009-November/5481981.html
		Ivan Maidanski <ivmai@mail.ru>

		64 bit/ 32 bit fallback of loadlibrary
		Nathan A. Sweet <nate@n4te.com>

		http://mailman.qbang.org/pipermail/rxtx/2009-November/5482004.html
		regenerated gnu_io_RXTXPort.h and gnu_io_RXTXCommDriver.h;
		changed version string returned nativeGetVersion();
		moved nativeGetVersion() to RXTXVersion;
		added native_psmisc_report_owner() (same as for Win32);
		removed unnecessary GetLastError() calls;
		added explicit WCHAR-to-jchar casts (and vice versa) where the
		compiler complains (same for LPWSTR and for "const" qualifier);
		adjusted some debugging messages (to also print returned error
		code);
		wrapped remaining printed error messages (and MessageBeep) into
		IF_DEBUG();
		made printj() defined only if DEBUG;
		replaced trailing "\n" with "\r\n" in printj();
		replaced "I" type char with "J" one for "eis" field;
		replaced get_java_int_var() with get_java_var_long();
		changed nativeSetSerialPortParams() returned type to jboolean;
		added nativeClearCommInput() and readTerminatedArray()
		stubs (these should be implemented in future);
		removed "MonitorThreadCloseLock" field usage in eventLoop();
		commented out unused throw_java_exception(),
		get_java_boolean_var2() and removed get_java_boolean_var();
		replaced Sleep(0) call with Sleep(1) one in CommEventThread() (
		to make yielding a bit "more reliable" among threads with
		different priorities);
		replaced named event with an unnamed one in
		InitialiseEventInfoStruct() (see the note below);
		added new JAVAXCOMM_FRONTEND macro for convenience (if defined
		then PortInUseException and UnsupportedCommOperationException
		are used "javax.comm" package (old behavior) else from
		"gnu.io." one (default));
		commented out DllMain() definition (since it does no action,
		only consumes resources);
		updated Readme.
		WinCE compilation fixes an updates
		readArray() simplified loop/fix pointer

		read() will toss an IOException (caught in the
		examples below but not in this library) if read
		thinks there will be a deadlock.
		Some small fixes found while merging with rxtx 2.0
		for public release.  Just sanity checks for library
		versions and such.

		fix for lockup found.
		removed Python and Cygwin code (ZystemImp.c)

		API but now it appears to work with it -crazy

		library) for logging over the network. Some
		attempts to fix lockup bugs.
		-pedantic compile passes.

		tcrash.m does not crash (W2K SP2)
		suite serial passes (W2K SP2)
		debug for flow control and parity switched off.
2.1-7pre5
		Later stage tinkering with flowcontrol and parity
		fixes.  Possibly bugs (w32 has many ways this can
		be setup).
2.1-7pre4
		testRead() now uses //./COM9 to verify port is
		usable (fixes bug introduced in pre3)
		build used java/jar/javac 1.3.1_06-b01
		-- initial tinkering with parity --
2.1-7pre3
		fixed //./COM?? so matlab can do s=serial('COM16')
		-- needed to test tcrash.m

1.2pre7 Oct 14, 1998  Various Fixes
1.2pre6 Oct  6, 1998  cleaned up documentation.  Pulled out win32 support.
		      Makefile.am remove full path from JAR command.
1.2pre5 Aug 12, 1998  Added David Atkinson's support for which implements event
		      notification, hardware flow control (tested with a modem),
		      multiple bytes reads etc.  Needs to be converted back to
		      termios calls.  Claims to work with blackbox.
		      .cvsignore - Added to ignore generated files such as 
		      "config.h".  It just cleans up CVS reports of what's new 
		      and different.
		      Makefile.am - Add a "jcl.jar" target to make a JAR file 
		      for JCL.
		      SerialImp.c - Implemented SerialInputStream_skip().  If 
		      it runs out of memory it uses a slower algorithm which 
		      uses almost no memory.  
		      - Support for baud rates of 38400.  - Rename get_speed to 
		      bps2speed_t (bits-per-second to speed_t constant) to 
		      remove ambiguity.  
		      - The GetSpeed functions now correctly return the bps 
		      speed rather than the speed_t constant.  This means JCL 
		      will now return the correct speed.
		      - Add speed_t2bps to be the reverse of bps2speed_t.
		      - Fix the spelling of "receive".
		      Added /dev/modem to the list of ports because it's very 
		      common.  Added comments from Suns NullDriver sample, 
		      giving credit where necessary.  (Sheldon Young - 
		      sheldon_young@yahoo.com)
		      Commented SerialImp.c (taj@www.linux.org.uk)
1.2pre4 Aug 12, 1998  The CommAPI has changed in the newest beta from Sun,
		      now named "javacomm20-ea".  I have attached RXTXPort.java,
		      which I have modified so it now compiles.
		      Sheldon Young sheldon@intergate.bc.ca
1.2pre3 July 5, 1998  libtool 1.0h, automake 1.3, (redhat-5.1 defaults)
		      added JDK_HOME as and option to configure.
		      missing string control to termios (in progress).

		      (doc and JDK_HOME changes suggested by 
		      fred@rodan.moremagic.com)
		      IOExeption work.

		      Added libtool support.  This should fix most Unix
		      porting problems.

1.1.1p0 May 21, 1997  Support for jdk 1.1.1.  Dropped support for 1.0.2
		      because of the jni in 1.1.1.  The native code required 
		      many changes.
0.50    Mar 17, 1997  Buffered input/output use of FileDescriptors.  Removed 
		      most of the native code.  deleted RO.java.  
0.22    Mar 14, 1997  Everything is now controlled from Main.java.  renamed 
		      classes for easier reading.  debug info for open(), 
		      write().  prevent reading from bad fd.  dump hex for RX 
		      as an example in RO.java.
0.21    Mar 12, 1997  Removal of hard coded vars Makefile Removed the last 
		      remnants of my GPS program.  Fixed Main.java by making it
		      wait for TX to finish (thanks to oliver) Irix support. 
		      (thanks to oliver)
