I spoke too soon.  What's running fine on Linux doesn't work on Windows.
Same problem.  inet:setopts always returns ok.  inet:getopts prior to a
send returns {active, once}

Does anyone have a suggestion of some source code that implements
gen_server behavior, receiving from a socket via handle_info()?  I'm not
finding much in google.

Thanks,
