Product Release History for PowerTCP Emulation for .NET
The following is a list of public releases for all components shipped with PowerTCP Emulation for .NET (Latest Release 2017-09-25)
PowerTCP Emulation for .NET
Current Version: 4.7.2.0
4.7.2.0 Released: 2017-09-25
Product fixes in this release:
- A issue where the *, -, and + numpad keys would not generate PF3, PF4, and -, as documented, has been resolved. (1018)
4.7.1.0 Released: 2017-03-08
- Visual Studio 2017 compatibility.
4.7.0.1 Released: 2016-06-21
Developer Note:
- An interface change was required in order to provide improved rendering and performance. Vt.BufferRows is now read only and Vt.BufferRows must be changed to Vt.MaxBufferRows whenever it is being set to indicate the maximum number of buffer rows for the scrollback buffer. Vt.BufferRows now represents the number of buffer rows currently populated and should still be used when setting properties like Vt.AutoScrollRowPosition.
- Columns are no longer limited to 80 or 132
Product fixes in this release:
- Using ALT+NUMPAD to generate characters while Vt.Keypad is numeric will result in the correct character output. (695)
- Various rendering fixes related to scrolling regions. (704, 744, 748)
- When sending, the Log event logs what is actually sent over the connection, instead of what keys are pressed. Ex: Pressing the up arrow results in the byte array 27,91,65 being logged instead of the single byte 38. (895)
- Characters partially rendered or not rendered in some fonts (Courier New & Lucidia Console) when the font size is set too small. (905)
4.6.0.6 Released: 2014-12-04
- Improved CPU usage in most scenarios.
- Significantly improved rendering speed resulting a more responsive UI experience.
- Improved support for National Character Set and Multinational mode operation.
- A ConnectTimeout property has been added to the Telnet component.
- A log event was added to the VT in order to log Client/Server data more easily when using SetStream.
- A TextRenderingHint property has been added so that developers can specify which type of text rendering to use.
- A ConnectTimeout property was added to TcpSession class.
Product fixes in this release:
- National Character Sets will no longer be set to ASCII erroneously. (239)
- An issue where 8-bit escape sequences were sometimes erroneously being processed in 7-bit mode has been addressed. (291)
- An issue where the control could hang due to an incompatibility with some printer drivers (Ex. CutePDF) when the PrintType property was set to auto or controller has been resolved. (365)
- The component will no longer incorrectly adhere to margins applied with DECSTBM. (513)
- Line insertion now works correctly within the VI text editor. (598)
