Problem is that in PROMPTED mode every time dsmcad is run it opens
some random high port, and you can never know what it is.
# netstat -tlpn | grep dsmc
tcp        0      0 0.0.0.0:32769               0.0.0.0:*
     LISTEN      4024/dsmcad
tcp        0      0 0.0.0.0:1581                0.0.0.0:*
     LISTEN      4024/dsmcad
# pkill dsmcad
# dsmcad
# netstat -tlpn | grep dsmc
tcp        0      0 0.0.0.0:37376               0.0.0.0:*
     LISTEN      14716/dsmcad
tcp        0      0 0.0.0.0:1581                0.0.0.0:*
     LISTEN      14716/dsmcad

that means that firewall admin needs to open up a whole range of high
TCP ports between particular client and the server which is not very
good security wise and plain ugly.
If client sits behind NAT, using POLLING mode is the only way to go IMHO.

 Your Firewall/NAT admin(s) should be able to tell you which ports
they see communications attempted.
