    So that's an executable you have to run and it writes the data stream to stdout?

      Yes, the stream comes through as stdout which I can redirect as input to the perl script.

        The your simplest approach would be to use a piped open. Something like this:

        #! perl -w
use strict;

open STREAM, './receivetest |' or die $!;

while( my $line = <STREAM> ) {
    print $line;
}

        That should get you started. Come back with questions arising.
