Hello, I could use the component TWSocketServer based on this example: http://edn.embarcadero.com/br/article/20465 now it seems to be working perfectly connecting to POS terminals, is correct to use in this instance? can continue to develop with reference it? a question .. when the connection is terminated the client side, or simply strip the cable network, the server is terminated after some time (timeout)?
