ethernet bps more than rs232 bps and if Ethernet send continuously

I have a question, the Ethernet bps more than Rs232 bps and if Ethernet send continuously by WIZ750SR-100 board, so what’s going to happen?

Hi.
If the speed of data transfer through serial communication is greater than the speed of data transfer over Ethernet, data is saved in the serial buffer and data loss may occur if the size of the serial buffer is exceeded.
You can solve this problem by activating the CTS and RTS functions.

oh~thanks, great reply, thank you very much
