Error handling

Bob Cowdery-4
I have a node on a RaspberryPi and am spawning a process on there from
another PC. The Pi process is failing to start because the appropriate
hardware is not connected so its throwing an exception. However, the
only information that the spawning process gets is **Can not start ...
on ... **. The Pi node does not report the error. It makes no difference
if I use spawn or spawn_link. How do I get the exception information
back to my spawning process.

Bob
