The window scale question

[weiyixuan]

When the TCP sender (a Windows application) is notified that the receiver has 1054 bytes left in the receiving window, the sender stops sending data, and the receiver (using netstack) does not consider itself in a zero window. It is found that the Windows scale is 5. Is there an interface that can modify the Windows scale value? Or why doesn't the sender continue to send data?

Is the algorithm for zeroReceiveWindow too simple?
