Docklight / Docklight Scripting V2.3.26
Copyright 2020 Flachmann und Heggelbacher GbR (www.fuh-edv.de)

Program Description:
Docklight is a test, analysis and simulation tool for serial communication 
protocols (RS232, RS485/422 and others). It allows you to monitor the 
communication between two serial devices or to test the serial communication
of a single device. Docklight is easy to use and runs on almost any standard 
PC using Windows 10, Windows 8 or Windows 7 operating system.

Docklight Scripting provides an easy-to-use program language and a built-in 
editor to create and run automated test jobs. In addition to COM ports (RS232, ...), 
Docklight Scripting supports TCP, UDP, USB HID or Named Pipes.

Installation:
- Run DocklightSetup.exe (resp. DocklightScriptingSetup.exe)

Distribution:
- See the fuh_distribute_int.txt file

Version History:

Docklight / Docklight Scripting V2.3.26 (03/2020)
Fixes and Improvements:
- Fixed bug with handshake status indicator box (was not continously updated). 
- Scripting: Fixed bug with DL.SetOutputText when appending text continuously.
  Content was not limited correctly, now RTF content is limited to approx. 510000 characters. 

Docklight / Docklight Scripting V2.3.25 (02/2020)
Fixes and Improvements:
- Fixed bug with Edit Send Sequence / Edit Receive Sequence dialog: 
  The dialog was in "Sequence modified / Apply" state immediately after opening, 
  even if no change was made. 	
- Experimental "lower system impact mode" for special applications with continuous communication.
  Please contact support on more information about how to use this mode.
 
Docklight / Docklight Scripting V2.3.23 (12/2019)
New features and functions:
- Project and Sequence documentation: 
  The lower right area of the Docklight main screen is now a  documentation area, 
  replacing the previous "Docklight Notepad". 
  Individual documentation can be added to each Send Sequence and Receive Sequence.
- Collapsable Send/Receive Sequence area to allow more space for the communication window
- New Receive Sequence Comment Macro %_S can be used to play the 
  default Windows notification sound.
- Scripting: New DL.SetUserOutput method to create independent output tab for 
  visual user feedback & interaction (using DL.GetKeyState, see below):
  DL.SetUserOutput(<text>, <rtfFormat>, <append>, <readFromFile>)
  <text>: The text to use/add. If empty string (""), hide the user output area again. 
          Default is vbCrLf = add line break
  <rtfFormat>: False (default) = text is plain text. True = <text> is a RTF document
  <append>: True (default) = add to the existing output. False = replace the existing output
  <readFromFile>: False (default) = <text> is the actual content. True = <text> is a file path that should be loaded
- Scripting: New DL.SetWindowLayout method to control the Docklight main window appearance
- Scripting: New DL.GetKeyState function to obtain current keyboard state, 
  compatible to Windows GetKeyState() API function and documentation. See user manual. 
- Pro Tap / Tap 485 communication scan (baud rate scan): 
  In Docklight VTP channel setting, set baud rate to None (0) to perform a continuous baud rate scan
  for both communication directions independently. See Docklight User Manual, Project Settings for details.
- "Start Logging" dialog and DL.StartLogging method now support RTF output format as an alternative to HTML. 
  Use extended syntax DL.StartLogging "d:\test", false, "AH", <format>
  with: <format> = 0 or False : plain text 
	<format> = 1 or True : HTML
	<format> = 2 : RTF 
- Scripting: DL.ShellRun to launch external application:
  result = DL.ShellRun(<operation>, <file> [, <parameters>] [, <directory>] [, <showCmd> = 10])
  e.g. result = DL.ShellRun("open", "notepad.exe", "log_asc.test"). See user manual. 
- Scripting: Multichannel / side channel support for opening additional data streams. See user manual 
  for "Side Channels".
  
Fixes and Improvements:
- hotplug / reconnect / auto-recovery for COM, HID and TAP connections. You are able to unplug and replug 
  USB devices like USB-to-RS232 interfaces during communication. An error will be displayed during the 
  interruption and communication resumes after reconnecting the USB device.

- Fixed Edit Send/Receive Sequence dialog bug on some non-ANSI locales: 
  when switching HEX -> ASCII -> HEX, character codes greater than 7F were changed to 7F.

  (please consider limitations in Docklight's overall data throughput!) 
- Scripting: USBHID allows product ID PID = 0 now.

New features and functions:
- New Docklight edition "Scripting" with built-in script editor for automated testing.
  Available as an upgrade for Docklight standard users. 
Fixes & Improvements:
- Non-standard baud rates can be used: Type any integer number between 110 and 999999
  in the corresponding dialog box. If the chosen rate is actually applied, depends on 
  the serial UART you are using. Non-standard baud rates may not work correctly when 
  "Flow Control" options are used.
- New Mode "Flow Control: Hardware Handshaking - RTS/CTS (Single Byte Mode):
  A sequence is placed byte-by-byte into the transmit buffer and CTS is checked before 
  each new character.
- New mode "Flow Control: RTS high while sending". This is to support RS485
  converters and related applications where the transceiver requires the PCs RTS signal
  to enable/disable the transmission.
- Improved communication processing and timing accuracy, which makes the "TweakComm" 
  utility provided to some users obsolete.
- ASCII Communication Window: Uniform behavior for different end-of-line standards:
  CR only, CR+LF, LF+CR

V1.3.38 (01/2004)
Fixes:

  moving to the empty sequence at the end of the list (Index ">" button) and
  pasting into the empty sequence.
- Fixed bug: crash when trying to paste a very large document (> 32K) from clipboard.

V1.3 (11/2003)

- New receive sequence actions: insert time stamp, stop communication
- New time stamp options: pause detection, e.g. for RS485 monitoring.
