In GNU Emacs (I have 18.48 on an Apollo) is there a way to determine when a
process has completed its output and is awaiting input?  I seem to remember
this being possible in Unipress Emacs, but I can't find a way to do it with
GNU Emacs.

I am trying to write a mode in which there is synchronous communication
between Emacs and a process that is started by Emacs.  By synchronous I mean
that I would like to
        1) send a command to the process
        2) wait for the process to complete its output based on the command
        3) "massage" the output, based on the command that was sent

Using a filter function doesn't work, because it can't tell when the output
has been completed (or can it?).
