Patent Information
Release NotesNew Firmware for USB and ExpressCard Hardware
NI-Serial 3.5.1 included new firmware for USB and ExpressCard serial interfaces. If you are upgrading from a version older than NI-Serial 3.5.1, you should disconnect and reconnect your USB and ExpressCard devices to update to the latest firmware after finishing the NI-Serial installation process. In the case of the USB-485/4 hardware, you should also disconnect and reconnect the power cable.
Port Enumeration Order on Windows 7 and later
Serial ports on Windows 7 and later may not enumerate in numerical order. For more information, go to ni.com/kb and search for KnowledgeBase 51RBTPG2.
Upgrading from earlier versions of Windows
Microsoft often supports upgrading to newer versions of Windows, without a complete system reinstall. This can cause an improper version of NI-Serial to be installed on the system, which does not properly support the upgraded operating system. You should uninstall NI-Serial prior to upgrading Windows, then download and install the appropriate version of NI-Serial for your new version of Windows.
If you have already upgraded Windows, without first uninstalling NI-Serial, it may be necessary to repair your NI-Serial installation. If the installed version does not support your operating system, you should then uninstall it and install the proper version.
Incorrect Serial Number Displayed in Measurement & Automation Explorer and the Device Manager
If you swap one PCI-based (PCI, PCIe, PXI, and PXIe) serial card for another of the same model, the serial number shown in Measurement & Automation Explorer and the Device Manager may not change. This happens because Windows cannot distinguish the old hardware from the new. To fix this problem, uninstall the interface through Device Manager, then scan for new hardware or restart your computer. This forces Windows to reinstall your hardware and the correct serial number will be displayed.
CreateFile COM Name Issue
The CreateFile function from the Microsoft Win32 API fails for port names COM10 and greater. To use these ports, and for the function to succeed, append the string "\\.\" before the port name. For example, to open COM10, use the string "\\.\COM10" for the port name. This is because the port's full name is actually \.COM10, and all "" characters must be doubled per the C language syntax.
Windows Server 2003 R2
Support for Windows Server 2003 R2 may require disabling physical address extensions (PAE). To learn how this might affect your use of Windows Server 2003 and what actions you might have to take, visit ni.com/info and enter the info code PAESupport.
Changes and Fixed Issues in Version 3.9Adds 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.
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.
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 SerialPort 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 3.8.1305387: DRIVER_IRQL_NOT_LESS_OR_EQUAL caused by NI-Serial ENET driver
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.
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.
Changes and Fixed Issues in Version 3.8Added support for cRIO-908x Controllers
NI-Serial 3.8 adds support for the RS-485 port of the cRIO-908x controllers running Windows.
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.
Changes impacting PCI, PCI Express, PXI, and PXI Express hardware:
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 843x series hardware.
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 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 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
NI-Serial 3.7 adds new hardware support for LabVIEW Real-Time. Refer to the NI-Serial for LabVIEW Real-Time readme for more information.
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.
Add support for PXI Express serial hardware
NI-Serial 3.6 adds support for National Instruments PXI Express serial interfaces. Refer to Supported Interfaces for detailed model information.
PXIe-8431 hardware adds support for higher baud rates
For some applications, it may be possible to use a PXIe-8431 interface for communicating at up to 10 MBaud. For more information go to ni.com/kb and search for 58KEI82F.
ID 201827: Incorrect RS-485 wire mode setting could be used when opening port
Changing the RS-485 wire mode for PCI, PXI, and PCIe devices in Measurement & Automation Explorer and Device Manager had no effect. This has been fixed.
Windows 2000

Support for PCMCIA-232 and PCMCIA-485 interfaces is discontinued in this release.
ID 34931: Timeouts when reading from ENET Serial ports
On some systems, every read attempt from an ENET Serial port would result in a timeout. This has been fixed.
ID 167613: Incorrect RS-485 wire mode setting could be used when opening a port
Changing the RS-485 wire mode for PCI, PXI, and PCIe devices in Measurement & Automation Explorer and the Device Manager had no effect on the port until the system was rebooted. This has been fixed.
ID 163281: Baud rates for PCIe ports cannot be set to a non-standard baud rate
It was not possible to set a PCIe serial port to a non-standard baud rate in Measurement & Automation Explorer and the Device Manager when using NI-Serial 3.5.0. This has been fixed.
ID 189256: Renumbered COM ports not available until after reboot
Renumbered COM ports could not be used until after a reboot on systems with Microsoft User Account Control (UAC) enabled. This has been fixed. Renumbering ports on an ENET interface will continue to require a reboot.
Changes and Fixed Issues in Version 3.5Added support for PCI Express serial hardware
NI-Serial 3.5 adds support for National Instrument PCI Express serial interfaces. Refer to the chart of Supported Interfaces for detailed model information.
On-Chip Flow Control
NI-Serial 3.5 adds support for on-chip flow control. Previous driver versions implemented flow control in the driver, which in some circumstances could allow data loss. All PCI, PXI, and PCI Express interfaces now utilize on-chip RTS/CTS and XON/XOFF flow control. 8430-series hardware also supports on-chip DTR/DSR flow control.
ID 139396: Windows Direct Cable Connection
Previous versions of NI-Serial could cause a system hang when initiating a Windows Direct Cable Connection. This issue has been resolved for PCI, PXI, and PCI Express interfaces. Issues may still exist when using Windows Direct Cable Connection with other interface types.

Changes and Fixed Issues in Version 3.9Adds support for updated Smart CamerasSupport 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.
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.
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.
Changes and Fixed Issues in Version 3.8.1Support for New Controllers
NI-Serial 3.8.1 adds support for serial ports on RIO Mezzanine Cards.
SecondaryInterrupts option in niserial.dbs has been replaced
The SecondaryInterrupts option used in the niserial.dbs file has been replaced, and will no longer function. See the "Performance on LabVIEW Real-Time" section in the NI-Serial Help for more information.
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 3.8Performance 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 843x series hardware.
Support for New Controllers
NI-Serial 3.8 adds support for additional cRIO, sbRIO, and Smart Camera controllers.
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 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 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 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.
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 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 3.6Add support for PXI Express serial hardware
NI-Serial for LabVIEW Real-Time, Version 3.6, adds support for National Instruments PXI Express serial interfaces. Refer to the chart of Supported Interfaces for detailed model information.
NI PXIe-8431 hardware adds support for higher baud rates
For some applications, it may be possible to use a NI PXIe-8431 interface for communicating at up to 10 MBaud. For more information go to ni.com/kb and search for 58KEI82F.
PXI chassis and slot information
When upgrading to NI-Serial 3.6 on some configurations, port assignments may change. For best results, please identify all PXI chassis through Measurement & Automation Explorer.

On-chip flow control
NI-Serial for LabVIEW Real-Time, Version 3.5.2, adds support for on-chip flow control. Previous driver versions implemented flow control in the driver, which in some circumstances could allow data loss. All PCI, PXI, and PCI Express interfaces now utilize on-chip RTS/CTS flow control. 8430-series hardware also supports on-chip DTR/DSR and XON/XOFF flow control.
Performance changes for some cRIO, cFP, and sbRIO controllers:
NI-Serial 3.5.2 includes performance changes that impact cRIO-901x, cRIO-907x, sbRIO-96xx, and cFP-22xx controller families. This change greatly reduces the CPU overhead of reading data from the serial port at high speed. An impact of this change is that increased latency may be seen when reading small numbers of bytes from the serial port. For more information about this change and possible solutions if you have issues with the increased latency, visit ni.com/kb and search for Knowledgebase 55597DG2.
