Serial Data Forwarding¶
The next three NV parameters (13-15) affect the “forwarding” of buffered-up serial data (data that has been received over one of the serial ports).
The NV13 - Buffering Timeout and NV15 - Inter-character Timeout are (as you might expect) time-related. They affect time-driven triggers that can cause
serial data to be “pushed” to other parts of the system. In contrast, NV14 - Buffering Threshold is completely timing-independent
and is driven solely by the quantity of data that has been received. All three of these parameters can be tuned to
control when data that a SNAP node receives over a serial connection gets forwarded to other nodes. To control where
the data gets forwarded to, refer to the crossConnect() and uniConnect()
functions. For more information, refer the to the SNAP Users Guide.
