November 2011

==========================================================================

Release 2.20

* Support added for Airborne Direct Industrial device install wizard.

* Added option to decorate the friendly names displayed in Device Manager
  with the MAC address, the IP address, or both.


--------------------------------------------------------------------------

Release 2.10

* Support added for Airborne Direct Enterprise and Industrial devices.

* Fixed an incompatibility with certain .NET application components. 

* Revamped the friendly names displayed in Device Manager.


--------------------------------------------------------------------------

Release 2.00

* This driver set supports Windows 2000, XP, Vista, and Windows 7 on
  32-bit and 64-bit platforms.
 
--------------------------------------------------------------------------

Release 1.40

* Support added for new wireless SDS models.

* Fixed bug that caused reception of serial data to stop on rare occasions,
  forcing the user to close and reopen the port.  

* This driver release is not yet WHQL signed.

--------------------------------------------------------------------------

Release 1.31

* The installation has been updated to recognize the new "-400" MEI devices.

* No other functional changes.  There is no need to update existing 
  installations to this release unless you are adding a "-400" device.

* This driver release is not yet WHQL signed.

--------------------------------------------------------------------------

Release 1.30

* The "friendly name" shown in Device Manager now includes the IP address.

* The user interfaces in the Device Manager property sheet and associated
  dialog boxes are clearer and a bit more streamlined.

* Added support for upcoming "-400" models.

* Added real-time tracing instrumentation for troubleshooting purposes.
  (Disabled by default, enabled with help from technical support.)

* If the SDS' IP address is changed after installation, the drivers will
  use the new address the next time the serial port is opened.  (Previous
  releases required the drivers to be shut down and restarted, most easily
  done by rebooting the computer.)

* Added support for unattended scripted installation to the local subnet.

* Support for the Windows serial device enumeration filter driver,
  SERENUM, is now disabled by default.  SERENUM was found to cause
  boot problems on some computers, depending upon the mix of attached
  serial peripherals.  If you require this support, please refer to the
  QTETPT.INF file in the "Driver" subdirectory for details on how to
  edit that file and reenable SERENUM.

* Fixed a bug that caused a system crash with STOP 0xD1 in TCPIP.SYS.

--------------------------------------------------------------------------

Release 1.21

* TCP auto-reconnect feature added.  Drivers will attempt to recover
  a broken TCP connection if the serial port is open.

* Support added for Windows NT4.

* Fixed a bug that indirectly caused a system crash with stop code
  of either 0x0A or 0xD1.

--------------------------------------------------------------------------

Release 1.10

* Tightened up handling of atypical XON/XOFF cases.

* Extended IOCTL_SERIAL_PURGE handling of clear commands to include
  the buffers resident in the SDS device in addition to the buffers
  in the driver.

* Bug fix:  Prexisting flow control were not being released when
  new flow control settings were sent to the driver by the application.

* Bug fix:  Characters marked with parity errors were being discarded
  if no error substitution character was defined by the application.
  These characters are now retained if no error substitution character
  is defined.

* Enabled automatic detection of attached external modems (via serenum).

--------------------------------------------------------------------------

Release 1.00

* Initial release.
