Wiznet 5100 as a server

hello everyone,
i use my wiznet as a server and i like to know if i can talk with multiply clients on the same socket or only with one client at the time?
if no,
what will my wiznet suppost to answere to a new client that try to communicate with a busy socket?

thanks .


If TCP, one server has one client. But UDP one server can receive several client data.
It is protocol, so anybody cannot change it.
