Well - there is no firewall between the UDS-10 and the server. I will try to get you the netstat output by tomorrow, because it takes a while before it stops logging. Thanks in advance for all your help - I almost re-wrote the code in C++ to see if I had more luck. Here is the netstat output when it's working: 
tcp        0      0 localhost:36903 uds-10#1:10001  ESTABLISHED
tcp        0      0 localhost:36939 uds-10#2:10001  ESTABLISHED

If you want to see more detailed netstat info in my next post, let me know.
