Hi,

thanks for response and yes, I'm sorry - wasn't specific enough....

Another try. I have command line utility that communicates with central software router under LMCE system. Whatever script receives from router it sends to stdout and whatever it receives on stdin, will be sent to router.

Therefore I need to have two way communication with that script from my Perl app.

Here is the code I'm trying, but get nothing (utility works from command line - it sends string to stdout) : 
#! /usr/bin/perl

use warnings;
use strict;

use IPC::Open2;

my $pid = open2 my $out, my $in, "/usr/pluto/bin/DCE-Whisperer -d 38 -
+r 192.168.0.51";
die "$0: open2: $!" unless defined $pid;

#print $in "PING";

my $sum=undef;
while (1) {
    $sum = <$out>;
       if ($sum) {
           print ("Got from DCERouter(out): $sum\n") ;
        print $in "reply txt OK\n";
        $sum=undef;
    };
 } ;     



close $in or warn "$0: close: $!";  
close $out or warn "$0: close: $!";

Thanks in advance for any help...

regards,

Rob.
