What's new in version 1.5.0

  • Added configuration option for software supported flow control.
  • Added configuration option for blocking keystrokes while transmit data flow is halted.
  • Added printing for plain text and hex views.
  • Added proxy settings to preferences (for update check).
  • Changed preferences window to multi-tab concept.
  • Made formatting of captured hex data configurable.
  • It is now possible to use the 'Wait for termination string' option when capturing in hex format as long as formatting of hex data is disabled.
  • Added "Packet Delay" option, which allows inserting a delay after the transmission of each packet, the size of which can now be specified via the connection settings GUI.
  • The "Line Delay" option now supports matching all of the specified delay characters in addition to matching any of them. This allows for entire strings to be specified as line delay characters.
  • Changed text encoding in "Send String" window to use system default encoding.
  • Improved GUI for flow control settings to prevent hardware and software flow control from being enabled at the same time.
  • Enhanced the behavior of the TX LED. When flow control is enabled and transmission is halted by the remote target, the color of the TX LED is changed to red to indicate that no data is being sent (select platforms only).
  • The reception of break signals or framing errors now flashes the RX LED red when "Ignore receive errors" is enabled (select platforms only).
  • Changed code to prevent the transmit progress from being displayed when "loop back receive data" is enabled and larger amounts of data are being looped back.
  • [Win/Linux] Changed behavior of modal windows such as connection options and send progress windows so that only the parent terminal window is blocked as opposed to all open windows.
  • [Mac] Added the following ApplesScript command:
  •         LookAheadHex(ID as integer) as String
  • [Mac] Removed the following AppleScript commands:
  •         Str2Hex(PlainStr as String) as String
            Hex2Str(HexStr as String) as String
  • [Mac] Universal Builds for Mac are no longer supported.
  • [Mac] Disabled SmartQuotes, SmartDashes, and SmartTextReplacement in TextArea.
  • Added handling of OutOfMemoryExceptions in transmit thread.
  • revised code to exclude text input line used in "Line Mode" from text size changes.
