TWedge: Version History

Version history, improvements, updates, hot-fixes and bug-fixes for the keyboard wedge software TWedge.

This software wedge provides universal data acquisition for serial or TCP/IP devices (RS232, COM, Bluetooth, USB) like barcode scanners, bar code readers, scales and gauges.

 

2010/02/16

V2.4.0.13122

Bug Fixes:
  • Online Product Activation
    Some systems displayed the activating/licensing dialogues in German instead of English language.

2010/02/01

V2.4.0

Bug Fixes:
  • TCP/IP and Bluetooth Connectivity
    Under some circumstances a new TCP/IP or Bluetooth connection timed out during open (e.g. with slow network speed).
  • Null-Byte Awareness
    Some problems were fixed.
  • Online Activation
    From now the online activation works only with V2.4 or higher.

2009/11/13

V2.3.0

Enhancements:
  • Display Device Data
    TWedge usually displays received device data in the protocol window. This behaviour is now adjustable in the Preferences dialog.
  • Display Hexadecimal Data
    Instead of displaying the received device data as ASCII characters, the data can be logged in hexadecimal notation. This behaviour is now adjustable in the Preferences dialog.
  • Online Activation
    TWedge can now be activated online. Manual licensing is still possible if no Internet connectivity is given or if this method is preferred for some other reason.
  • RFID Controller Access
    Included are now Javascript samples for reading RFID Tags from EMS RFID Controllers (ABx Fast protocol).
Bug Fixes:
  • Null-Byte Awareness
    The new version of TWedge sends and receives data with 0-bytes (NUL - \x00) correctly. In previous versions data containing 0-bytes was truncated.
  • Input Validation
    The user input in the dialog Data Packets is now validated correctly.

V2.2.0

Enhancements:
  • Native Bluetooth Support
    Version 2.2 is now able to connect to Bluetooth devices directly. What's the advantage? Virtual COM ports are not needed anymore and TWedge reconnects to lost connections automatically! Just select the Bluetooth device in the Interface dialog or enter the address of your Bluetooth device directly (e.g. 00:0c:a7:01:ce:de). The Bluetooth address is usually printed on devices like Bluetooth barcode readers. Another possibility to check out this address is in the Bluetooth Devices section of the Windows Control Panel Control Panel\Hardware and Sound\Bluetooth Devices.
  • Automatic Connection Restore
    For Bluetooth® and TCP/IP connections TWedge restores lost connections (e.g. out of range in the case of Bluetooth) automatically.
  • Update Check
    You can check if there is a newer version of TWedge available by clicking Help -> Check for Update...
Bug Fixes:
  • JavaScript
    The function MessageBox() now returns correct values and the return values are now defined in the script editor.
  • Help-Texts
    The help-texts for some database functions were corrected.

V2.1.2.0

Enhancements:

Due to customer feedback the keystroke simulation was improved to offer better support for Remote Desktop Clients (RDP) and Citrix® XenApp®:

  • SendKeyStrokes Function
    The SendKeyStrokes() function can now be called with an additional parameter to wait for some time after every character was sent. This is useful when the receiving application needs some time to process the keystroke (e.g. sending over a remote desktop connection). If no delay is specified, TWedge uses by default 10 milliseconds.
  • Clipboard Functions
    The clipboard functions CopyToClipboard() and GetFromClipboard() were enhanced to retry the operation if the function fails. The number of retries and the time to wait after every retry can be specified by calling the function with 2 additional parameters. Default values are 5 retries with 100 milliseconds delay between retries.

V2.1.1.0

Bug Fix:
  • The format of the TWI files was changed. This ensures that saving TWedge settings also works if special characters (like STX, ETX, EOT, DC1, DC2, ...) are part of the script. TWI files from previous version can be loaded without problems.

    TWI files are saved always in the new format! Previous versions cannot read the Javascript of V2.1.1 format!

2009/04/29

V2.1.0.0

New
  • The new function InputBox() can be used to ask the user for input during runtime (supports optional input validation).
  • The clipboard access functions CopyToClipboard() and GetFromClipboard() were introduced. These functions are useful for larger amounts of data, where a simulation of keystrokes is not feasible or too slow.
  • The function SendKeyStrokes() now accepts combinations of key constants and modifier keys. The keys have to be separated by a + character (e.g.: "{CTRL+f}" or "{CTRL+SHIFT+h}").
  • Toolbar and application icons were redesigned.

2008/10/11

V2.0.0.0

New
  • JavaScript support (script-based data-acquisition)
  • Direct database access via ODBC
  • Direct file access (read/write)
  • Hot key support (freely adjustable, script-based hotkey function)
  • Timer support (freely adjustable, script-based timer function)
  • Bi-directional device communication
  • Encrypted and password protected configuration files, end-users are not able to change data acquisition scripts.
  • Easy deployment of data acquisition scripts (self-licensed scripts)
  • Test-data functionality for script-development

2007/09/02

V1.2.1.12

New:
  • Beep sound when pressing the Hot Key can be turned on/off in the TWI file now

2007/04/18

V1.2.1.11

Bug Fix:
  • Problem with AVM bluetooth stick was solved.

2005/08/10

V1.2.0.10

New:
  • Hotkey function for sending data.

2005/07/12

V1.1.1.9

Bug Fix:
  • There is no semicolon saved in the translation table (it can't be read from the ini file).

2005/03/22

V1.1.1.8

New:
  • A "negative" time out was introduced. This is intended for scales which sends data continuously (until its load stabilizes). This timeout must be at least elapsed, before the last data package will be sent.

2003/06/17

V1.0.1.6

Bug Fix:
  • If the "=" sign was used as trigger for the control sequence table, this setting will not be read when the ini files are reloaded.
