Thanks Mathias, i´ll see your file. I don´t know the protocol because i´ve
readed the customer documentation and it doesn´t say anything about
protocol.
"

links connection process shall be initiated by the PC unit: it will connect
sequentially (one after the other) all the logical links.

At power-on/reset, the EVK-1100 Unit shall first create the sockets in order
to be ready for accepting a connection in all of them."


the connection are permanent maybe will be TCP no? because then there is a
diconnect process.


i´ll need 8 socket TCP connection permanent , do you think the same?


Regards

Oscar
