- * Handle network signals (signals).
- * Signals always have return status 0 from bnet_recv() and
- * a zero or negative message length.
- * Pass appropriate messages back to the caller (responses).
- * Responses always have a digit as the first character.
- * Handle requests for message and catalog services (requests).
- * Requests are any message that does not begin with a digit.
