The connection is created as follows:

NSSocketPort *clientPort = [[NSSocketPort alloc] 
initRemoteWithProtocolFamily:PF_INET socketType:SOCK_STREAM 
protocol:IPPROTO_TCP address:serverAddress];
NSConnection *clientConnection=[[NSConnection alloc] 
initWithReceivePort:nil sendPort:clientPort];
[clientConnection setRootObject:self];
[clientConnection setRequestTimeout:2.0];
[clientConnection setReplyTimeout:5.0];

Thanks

Guy
