I'm writing a server using PERL (I'm running a Windows XP system). It needs to write some data to the an external console application and capture and process it's output. I looked through the web and found the IPC::Run module. It seemed to be, what I needed. At first I wrote a test program like that - 
use IPC::Run qw(start pump finish);

my @args;
push @args, $app_path;
my ($in, $out, $err);

# starting the application
my $handle = start \@args, \$in, \$out, \$err;

# wait until prompted for input
pump $handle until $out =~ /Login:/;
$in .= "Boris\n";

# wait until prompted for password
pump $handle until $out =~ /Password:/;

# and so on ...

This script worked fine. But I needed to store the $in $out and $handle variables for further use. So I put them in the hash 
$client_descr->{"Handle"} = $handle;
$client_descr->{"In"} = $in;
$client_descr->{"Out"} = $out;
$client_descr->{"Err"} = $err;

But after that I had problems: From other sub I got $in $ out and $handle 
my ($handle, $in, $out) = ($client_descr->{"Handle"}, $client_descr->{
+"In"}, $client_descr->{"Out"});

But I had problems - here in this pump loop nothing seemed to happed. This pump loop was just locked. 
$in .= "new data\n";
pump $handle until $out =~ /data arrived:/;
print $out;

Is it true, that I can use IPC::Run only in one module? And are there any other solutions of my problem? I tried to ise Open2, but it doesn't seem to be working.
