NI-Serial 3.8 adds support for the RS-485 port of the cRIO-908x controllers running Windows.
NI-Spy has been replaced by NI I/O Trace.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 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.
