make-network-process: handling multiple calls to filter

[Miguel Guedes]

Hello list,

I'm creating an asynchronous network connection as given below: 

  (make-network-process :name      "connection-name"
                        :buffer    "*output-buffer*"
                        :host      om-address
                        :service   om-port
                        :filter    om-handler
                        :nowait    t
                        :sentinel  'om-sentinel))

The problem I'm having is om-handler, the filter, is sometimes called 
more than once depending on the amount of data the server sends back.

Is there a way of knowing when the last call to the filter is taking 
place so that final processing can occur?
