    Changes and Fixed Issues in Version 4.0Added support for NI CVS-1457RT Compact Vision SystemImproved Support for NI System Configuration API
    NI-Serial 4.0 adds the discovery of USB and ENET hardware, NI 9870 and NI 9871 modules through the NI System Configuration API.
    NI System Configuration Expert Name Change
    The NI System Configuration expert for NI-Serial has been renamed from "ni-serial" to "serial". This change allows for system configuration and MAX import/export operations to be accessed in a consistent manner. Existing applications using the old name must be updated.
    Improved Appearance in MAX
    NI-Serial 4.0 improves the way serial hardware is displayed in MAX. PXI and PXIe hardware are now displayed under their respective chassis in the tree, and ENET interfaces are now found under Network Devices. The port items which were previously shown in MAX have been removed, and VISA ASRL resources are now placed directly beneath the serial interface.
    NI 9870 and NI 9871 modules will also now appear in MAX when configured for use with NI-Serial. When using a host system with NI-Serial 4.0 installed to view LabVIEW Real-Time controllers running older versions of NI-Serial, the NI-Serial boards will no longer appear in MAX. All ports will still be accessible as VISA ASRL resources.
    Removal of NI-Serial Communicator
    NI-Serial Communicator has been obsoleted, and is no longer installed. Similar functionality can be found using NI-VISA Interactive Control, which can be opened by selecting a VISA ASRL resource in MAX, and clicking the Open VISA Test Panel button in the toolbar.
    ID 387524: Incorrect Slot and Chassis Identification
    When using the NI System Configuration API to query information about NI-Serial PCI or PCIe hardware in a Desktop RT system, it would incorrectly specify that the board was in slot 255 of chassis PXI255. This has been resolved, and now reports that the chassis and slot are unavailable.

    Changes and Fixed Issues in Version 3.9.1Update shortcuts installed on Windows 8
    When installing on Windows 8, NI-Serial no longer pins shortcuts to the Start screen. Shortcuts which are available from the start menu on earlier versions of Windows may be accessed through the NI Launcher utility, or by searching from the Start screen.
    ID 383662: Configuring ENET serial port to COM256 causes crash
    NI-Serial 3.9.1 resolves an issue where a system crash could occur after renaming an ENET-232 or ENET-485 serial port to COM256. This crash could occur either when opening the port, or immediately upon booting Windows.

    Changes and Fixed Issues in Version 3.9Added support for updated Smart CamerasAdds support for Windows 8
    NI-Serial 3.9 adds support for Windows 8. Known issues exist regarding the accessibility of items which were previously accessible via the Windows Start Menu. This will be addressed in a future release of NI-Serial.
    Support for NI System Configuration API
    NI-Serial 3.9 supports the discovery of PCI-based (PCI, PCIe, PXI, and PXIe) hardware through the NI System Configuration API.
    ID 359904: System Instability every 49.7 days
    NI-Serial 3.9 fixes an issue where various errors could be manifested if a serial transfer is in progress when the 32-bit system tick count rolls over, which happens once every 49.7 days. Symptoms included failed serial transfers, FIFO overruns, failure of serial transfers to timeout, and system hangs.
    ID 325477: Possible system crash after removing hardware during hibernation
    NI-Serial 3.9 resolves an issue where a system could crash after removing PCI-based hardware from a hibernated system. Depending on the system configuration, the crash could occur immediately upon resume, or at a later time.
    ID 317971: Cannot use baud rates higher than 131072 from .NET and possibly other applications
    NI-Serial 3.9 resolves an issue which limited the usable baud rate from the .NET Serial Port interface to 131072 baud. This error occurred because NI-Serial improperly reported the maximum baud rate as BAUD_128K (The maximum constant supported by the API) when the port actually supported higher baud rates. This has been changed to report BAUD_USER, indicating that custom baud rates are supported. Other applications querying the maximum baud rate may have been impacted as well.

    Changes and Fixed Issues in Version 3.8.2ID 347232: System could hang during reboot
    A system could hang during reboot if it was transmitting data from a 843x series serial port when the reboot command was sent. This has been fixed.
    ID 337167: Possible crash with cRIO-9075, cRIO-9076, sbRIO-9605, or sbRIO-9606 controllers
    A system crash or instability could occur when detecting serial ports on any of the mentioned controllers. Some examples when this could occur are expanding Devices & Interfaces in Measurement & Automation Explorer, installing VISA Server on the target, or attempting to use a serial port. This has been fixed.
    ID 328853: Serial ports not functioning on cFP-2100 and cFP-2110 controllers
    The serial ports on cFP-2100 and cFP-2110 controllers were not properly detected. This did not impact cFP-2120 controllers. This has been fixed.

    NI-Serial 3.8.1 has resolved issues which occasionally resulted in DRIVER_IRQL_NOT_LESS_OR_EQUAL system crashes when using ENET-232 or ENET-485 ports.
    ID 299891: IRQL_GT_ZERO_AT_SYSTEM_SERVICE caused by NI-Serial ENET driver
    NI-Serial 3.8.1 has resolved an issue which could result in a IRQL_GT_ZERO_AT_SYSTEM_SERVICE system crash when closing an ENET-232 or ENET-485 port.
    ID 132892: Incorrect behavior when using NI-VISA VI_EVENT_ASRL_RI event
    When using the VI_EVENT_ASRL_RI event with some cRIO, sbRIO, and cFP controllers, the event was incorrectly signaled on both rising and falling edges of the RI line. This behavior has now been fixed, and the event is signaled only on the falling edge.

    Changes and Fixed Issues in Version 3.8Added support for New Controllers
    NI-Serial 3.8 adds support for the RS-485 port of the cRIO-908x controllers running Windows.
    NI-Serial 3.8 also adds support for additional cRIO, sbRIO, and Smart Camera controllers.
    NI-Spy replaced by NI I/O Trace
    NI-Spy has been replaced by NI I/O Trace. All functionality previously found in NI-Spy is now found in NI I/O Trace.
    Performance Optimizations for Small Transfers
    Several enhancements have been made to improve performance and decrease CPU overhead when performing small writes on all interfaces, and small reads on NI 843x series hardware.
    Port numbering change for some systems
    NI-Serial now reserves port numbers for two built-in serial ports on all PXI, Industrial Controller, Desktop RT, and cRIO-908x controllers. On these systems, PnP hardware will now be assigned port numbers starting with COM3, when they may have previously been assigned COM2.
    NI-Serial settings no longer persist after uninstall
    The niserial.dbs file is replaced each time NI-Serial is uninstalled or reinstalled. This has the effect that any customized settings will be removed. This matches the behavior of NI-Serial 3.6 and earlier.
    Removed support for FP-20xx and cFP-20xx controllers.
    NI-Serial for LabVIEW Real-Time, Version 3.8, requires LabVIEW Real-Time 8.6 or later. It is not possible to install on FP-20xx or cFP-20xx controllers. These controllers will continue to work with previous versions of NI-Serial.
    ID 298769: Incorrect Parity Setting
    Mark and space parity were not properly configured on some cRIO, sbRIO, and cFP controllers. This has been fixed.
    ID 288089: Flow control may not disengage
    When using multiple forms of flow control simultaneously on a single port, it was possible for flow control to fail to disengage, preventing data transmission. This has been fixed.
    ID 288079: Possible crash when rebooting cRIO while using NI 987x modules
    It was possible for a cRIO controller to crash during reboot when using serial ports on a C Series module. This has been fixed.
    ID 287461: Possible loss of data preceding serial error
    Several bytes of valid data could be discarded immediately prior to the reception of a serial error, such as a parity or overrun error. This valid data is now properly received prior to handling the error condition.
    ID 286317: Data reception could halt
    When the RX FIFO became completely full on some cRIO, sbRIO, and cFP controllers, the port could stop receiving data. This has been fixed.
    ID 277876: Controller may hang on reboot
    In some rare circumstances, the process of shutting down serial ports for a reboot could cause the controller to hang. This has been fixed.
    ID 219314: Incorrect timeout behavior
    The special case where the Timeout Byte Interval and Timeout Multiplier are both -1 was handled incorrectly, resulting in serial calls failing to time out. This was most easily seen when using NI-Serial from .NET applications. This issue has been fixed.

    Changes and Fixed Issues in Version 3.7.1Add support for the NI cRIO-9075/6 Controller
    NI-Serial for LabVIEW Real-Time, Version 3.7.1, adds support for the NI cRIO-9075 and cRIO-9076 Controllers.

    Changes and Fixed Issues in Version 3.7NI 9870 and NI 9871 Modules
    NI-Serial 3.7 allows users to access the NI 9870 and 9871 modules directly from LabVIEW Real-Time 2010 without using the LabVIEW FPGA interface.
    To enable this support, install NI-Serial 3.7 and NI-VISA for LabVIEW Real-Time on a Compact RIO Target that supports RIO Scan Interface (RSI). When detecting the modules, users will have the option to add the module directly to the chassis in the LabVIEW project.
    If using NI-RIO 3.5.x and lower, you may see warning pop-ups indicating that the NI 987x modules are not supported on RSI. These warnings can be ignored. For more information go to ni.com/kb and search for 5DTFTOL1.
    Port Numbering Behavior
    NI-Serial 3.7 changes the way that ports are numbered when detecting boards. Under some circumstances inserting new boards into a system may cause port numbers to change. For more information go to ni.com/kb and search for 5D2G85G2.
    Serial Settings Persist after Uninstall
    The behavior of settings on uninstall was reverted in NI-Serial 3.8. Please refer to Changes and Fixed Issues in NI-Serial 3.8 for more information.
    Serial settings stored in the niserial.dbs file, including port numbers, will persist after uninstalling NI-Serial 3.7 from a Real-Time target. The modifications to the niserial.dbs file will also persist through reinstalls of the NI-Serial driver. To reset these settings to default, delete the niserial.dbs file from the Real-Time target.

    Changes and Fixed Issues in Version 3.6Windows Server 2003 R2 (32-bit) and Windows Server 2008 R2 Support
    NI-Serial 3.6 adds support for Windows Server 2003 R2 (32-bit) and Windows Server 2008 R2. Note that only the R2 versions are supported. Refer to Supported Interfaces for a list of supported hardware.
