Modtronix SBC65EC/SBC68EC Web Server
********************************************************************************
The Modtronix SBC65EC and SBC68EC Web Servers are web based single board computers.

********************
V3.10 - 2009 May 29
********************
- Fixed bug where configuration data was overwritten when configuring serial busses
- Application config now also saved to EEPROM for commands received via UDP
- Fixed some serial busses bugs
- Added a watchdog timer to the code. If the code locks up, the board will be reset within 1 second.
- Added event port. To activate event port, simple send any UDP message to port 54124. After this
  the SBC board will start streaming events to this port.
- Added "Expansion Board" feature to SBC65EC. It is now possible to configure the SBC65EC to work
  with a MXD2R or IOR5E expansion board.
- Fixed bug in cmdTask() function where wUpdate was not initialized with 0, causing application
  configuration functions to be randomly called.
- Fixed bug initializing CPU ports. This bug could have caused very short micro-second spikes on IO ports
  at start up. Sequence of calling appcfgCpuIO() and appcfgCpuIOValues() functions were fixed.


********************
V3.10 Beta1 - 2008 July 10 (cvs tag "pic_sbc65ec_websrvr_v310B1")
********************
- Added "Tag Request UDP Commands". This allows any tag value to be obtained via
  UDP commands. For example, to request the value of Port B6 via UDP, simple send
  "%b06" string to UDP port 54123, and it will be returned to you.
- Implemented 10-bit Analog To Digital converter code, and made 10-bit mode the
  default.
- Implemented Beta version of Serial Buses module. This allows two serial ports,
  and two UDP ports to be linked together via a web page. For example, serial port 2 and
  UDP port 1 can be linked via the configuration web page. This example will create a
  Serial to UDP interface converter.
- Replaced DHCP module with new code from Microchip V4.50
- Fixed bug in UDP command receiption where command was not correctly terminated
- Added cmdGetTag() function
- Implemented %n00 to %n0f tags for getting hex representation of Analog Input Channel.
- Implemented %w01 to %w04 tags for getting hex representation of PWM channel.

  stack, see "version.txt" file in "./src/net/" folder.
- Fixed bug with SBC68EC board where port pins F3, F4, F5 and F6 did not
  work correctly when configured as inputs.
- Fixed a couple of other minor bugs reported on user forum

********************
V3.05 - 2006 October 9 (cvs tag "pic_sbc65ec_websrvr_v305")
