Asked by Bhushan Mengale on 2018-04-10 in Serial-to-Ethernet & ConfigTool.

I am working with WIZnet WIZ750SR S2E module serial Inerface RS-422/485. It working properly in TCP server mode it receive data from Ethernet and print on Serial port as mention in link [\[Modules\] How to testing TCP connections?](https://forum.wiznet.io/t/topic/4278) but when it switch to TCP Client, TCP mix or UDP mode data is not send from serial to respective server or broadcast as UDP to all. Please help for the same.
