[R] Named pipe connections and stdout

I am trying to use a named pipe to steer R from an external application.
Following the examples in RNEWS 1:1, I have created a simple listener:
zz <- fifo("TESTFIFO", "r")
a <- readLines(zz)
if(length(a) != 0)
e <- try(eval(parse(text = a)))
if (inherits(e, "try-error"))
# error handling code here
I tested this by steering R from a simple console (e.g. using something
echo "<r-command> > TESTFIFO
This works OK but where has stdout gone?
