Hi Mark,
    I'm in a similar boat myself trying to learn OTP, and have found
the tutorial mentioned in this thread to be quite useful:

http://www.erlang.org/ml-archive/erlang-questions/200602/msg00035.html

It implements a gen_server using a port to communicate with an
external program, using a call to the gen_server.

Cheers,
      Matt
