Asterisk to send back the result code indicating that the application
execution is complete.  You'll get nack something like "200 result=0".

I tried it again, reading a single line from stdin and got the "200
result=0" message. Is there potential for there to be other messages? i.d.
"200 result=1" or "404 file not found"? Also, is there always going to be
a single line from stdin, or should I loop until I find the line I'm
looking for?

Thanks again,
Roy
