Great that was the problem - I had a
handle_call.....
->
port_command(....)
Receive
  Data ->
%do a match on the data here

in the handle_call and this was what was matching the
{'$gen_server',... . I had no idea that the gen_server messages will
be matched by this receive. Thanks a lot for clarifying that.
