Embedded TCP/IP stack: fnet_serial_flush

Sends data from the internal stream buffer to the stream client.

Parameters

stream

Stream descriptor.

This function immediately sends data from the internal stream buffer to the stream client.
If you do not explicitly call the flush function, stream sends data to the client after the internal buffer is full.
The function only has meaning for buffered streams.
UART stream does not have internal buffer and does not use this flush function.
