OpenTCP TCP window and Buffer Size

Im not sure how to adjust the "TCP window" buffer size. It seems that TCP_DEF_MTU macro is the most likely #define to adjust to be a larger window size, but not successful.

Ive configured the BUFMAP to the maximum receive and transmit buffers size and according to the docs it should give me a window size of 1536, but im still stuck at 512 byte.

I feel im missing something simple. Is there an auxilary buffer whose max MTU size is fixed at 512? How does the receive mechanism work.
