[Ace-users] [ace-users] Getting a TCP socket connection with a unique port perthread

[Steve Huston]

Hi Jim,

If you want the threads to use different sockets (and therefore
different local port numbers), make sure that tcpStream is not a
single object accessed via both threads.

Best regards,
-Steve
