+
+    * Bug fix, not blocking on transmit
+      by Erik Petrich, http://mbed.org/forum/bugs-suggestions/topic/2200
+      
+1.19    20 April 2011
+
+    * Fixed some doxygen comment bugs.
+    
+1.18    20 April 2011
+
+    * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type)
+      to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter
+      to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q).
+    * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type.
+      This class holds a pointer to the MODSERIAL object that invoked the callback
+      thus freeing callbacks need to use the global variable of the original 
+      MODSERIAL instance.
+    * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL
+      thus allowing certain functions to be restricted to callback context only.
+    * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function
+      to remove the character that was just placed into the RX buffer.

+
+1.17   08/Mar/2011
+       Fixed a memory leak in the DMA code.
+       
+1.16 - 12 Feb 2011
+    
+    * Missed one, doh!
+
+1.15 - 12 Feb 2011
+    
+    * Fixed some typos.
+    
+1.14 - 7 Feb 2011
+
+    * Fixed a bug in __putc() that caused the output buffer pointer to 
+      become corrupted.
+
+1.13 - 20/01/2011
+
+    * Added extra documentation.
+    * Fixed some typos.
+    
+1.12 - 20/01/2011
+
+    * Added new "autoDetectChar()" function. To use:-
+      1st: Add a callback to invoke when the char is detected:-        
+        .attach(&detectedChar, MODSERIAL::RxAutoDetect);
+      2nd: Send the char to detect.
+        .autoDectectChar('\n');
+      Whenever that char goes into the RX buffer your callback will be invoked.
+      Added example2.cpp to demo a simple messaging system using this auto feature.
+
+
+1.11 - 23/11/2010
+
+    * Fixed a minor issue with 1.10 missed an alteration of name change.
+    
+1.10 - 23/11/2010
+
+    * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete()
+    
+1.9 - 23/11/2010
+
+    * Added support for DMA sending of characters. Required is
+      the MODDMA library module:-
+      http://mbed.org/users/AjK/libraries/MODDMA/latest
+      See example_dma.cpp for more information.
+      
+1.8 - 22/11/2010
+
+    * Added code so that if a buffer is set to zero length then
+      MODSERIAL defaults to just using the FIFO for that stream
+      thus making the library "fall back" to teh same operation
+      that the Mbed Serial library performs.
+    * Removed dmaSend() function that should have been removed 
+      at 1.7
+    
+1.7 - 21/11/2010
+
+    * Remove the DMA enum from MODSERIAL.h as it's not currently 
+      ready for release.
+    * Added page doxygen comments.
+
+1.6 - 21/11/2010
+
+   * Version 1.5 solved a blocking problem on putc() when called 
+     from another ISR. However, isr_tx() invokes a callback of it's
+     own when a byte is tranferred from TX buffer to TX FIFO. User
+     programs may interpret that as an IRQ callback. That's an ISR
+     call from within an existing ISR which is not good. So the 
+     TxIrq callback from isr_tx is now conditional. It will only
+     be called when isr_tx() is actually within it's own ISR and
+     not when called from alternate ISR handlers.
+     
+1.5 - 21/11/2010
+
+    * Calling putc() (or any derived function that uses it like
+      printf()) while inside an interrupt service routine can
+      cause the system to lock up if the TX buffer is full. This
+      is because bytes are only transferred from the TX buffer to
+      the TX FIFO via the TX ISR. If we are, say in an RX ISR already,
+      then the TX ISR will never trigger. The TX buffer stays full and
+      there is never space to putc() the byte. So, while putc() blocks
+      waiting for space it calls isr_tx() to ensure if TX FIFO space
+      becomes available it will move bytes from the TX buffer to TX
+      FIFO thus removing the blocking condition within putc().
+
+1.4 - 21/11/2010
+
+    * Removed all the new DMA code. I wish mbed.org had proper SVN
+      versioning, I'm use to working in HEAD and BRANCHES after I've
+      released a project. Getting bug reports in current releases
+      while trying to dev new code is hard to manage without source
+      control of some type!
+
+1.3 - 21/11/2010
+
+    * Fixed a macro problem with txIsBusy()
+    * Started adding code to use "block data" sending using DMA
+    * Removed #include "IOMACROS.h"
+    
+1.2 - 21/11/2010
+
+    * Removed unsed variables from flushBuffer()
+    * Fixed a bug where both RX AND TX fifos are cleared/reset 
+      when just TX OR RX should be cleared.
+    * Fixed a bug that cleared IIR when in fact it should be left
+      alone so that any pending interrupt after flush is handled.
+    * Merged setBase() into init() as it wasn't required anywhere else.
+    * Changed init() to enforce _uidx is set by Serial to define the _base
+      address of the Uart in use.
+        
+1.1 - 20/11/2010
+
+    * Added this file
+    * Removed cruft from GETC.cpp
+    * "teh" should be "the", why do my fingers do that?
+
+1.0 - 20/11/2010
+
+    * First release.
