Thank you all for comments and suggestions. It would not have occurred to me to 
set the keep-alive value that small, I will try that. That is a lot less 
irritating than my print a char script that mucks up emails. In google I found 
someone suggesting setting "IPQoS throughput" in $HOME/.ssh/config. I am going 
to try both when I next go to a 100% fail location. I'll report back.

I also find it strange that sitting in pine triggers the timeout but sitting 
idle for days does not.
