Since the network packets are correct and the asyn trace shows the 
problem, I think that is is probably a stale buffer at some level.  The 
asyn tracing shows that the reply string to the command that timed out 
is passed as the reply to the next command sent.

There doesn't seem to be an obvious "Oh do this" answer, so I will dig 
into the code Monday and find out what is happening.

Thanks for the help,
