I noticed that a Revolution TCP client on W2K will time out in 21 
seconds.  Even Australia to Canada should connect in less than 
that, I think.

In my situation, the connection is actually established.  You might 
try checking with repeated netstat -p TCP.  Or use TCPmon to watch 
connections come and go.  Or, if your server is relatively quiet, 
look at traffic with Ethereal or a similar tool.

A stab in the dark.

I had to say that; we are on the use-revolution list.

I tried doing all the same things by script and it did not work.  
(Assuming we are seeing the same thing.)

The behavior on W2K is not the same as on OS X, the only other 
platform I checked.  On OS X, an open will get a socket open 
callback upon establishment, a socketClosed upon refusal, or a 
socketClosed in 75 seconds otherwise.  On Windows 2000, an open 
will get a socket open callback upon establishment (except for your 
and my situations ;-), a socket open callback if refused (delayed 
.9 seconds), and an open callback in 21 seconds if nobody is home.
