  4. J2ME GFCMIDP 2.0 = “Sockets” via URL • SocketConnection socket://server.app.dk:8080 (TCP) • SecureConnectionssl://server.app.dk:8081 • DataGramConnection datagram://server.app.dk:8082 • Serverside = socket://:8080 ssl:/::8081 datagram://::8082 • +´Seriel Comport comm:COM1 comm:COM2 • Husk Permissions
