Issues Fixed in the NI-Serial 3.9 Update

ID Description
359904 NI-Serial 3.9 fixes an issue in LabVIEW Real-Time 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.
325477 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 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.


The update is available via Update Service, or from the Drivers and Updates links below.
