I've got this problem where I can login, readline from a files in a directory and send them to a telnet terminal (HOSTA:5051). However, the output is being dumped on HOSTA:5005, which is non-interactive after logging in with user and password. I can actually select from which port I dump the output, i.e. from 5001-5029. But since there is no interaction with the dummy-terminal, I cannot figure out how to actually get an extensive dump of the command result I am sending. Hence, I am unable to trap any errors caused by the commands I send. Question is: whether the current Net::telnet module provide any thing to capture data from this sort of 'dummy telnet session'. I suspect it could be getline/get/buffer object. I am just no too sure how exactly either one of them works. here's the current script I am using to capture output:: 
use Net::Telnet;
use POSIX qw(strftime);

my $lognamevar = strftime "%y-%m-%d", localtime;
my $dumpscreen_in = "dmpscrn-in-".$lognamevar.".txt";
my $dumpscreen_out= "dmpscrn-out-".$lognamevar.".txt";
my $dumpscreen_dump= "dmpscrn-dmp-".$lognamevar.".txt";
my $user = "root";
my $pass = "root";

open(DMPSCRNIN, ">>$dumpscreen_in") || die "Cannot open Dumpscreen tel
+net on port 5005 for error-trapping:$!\n";
open(DMPSCRNOUT, ">>$dumpscreen_out") || die "Cannot open Dumpscreen t
+elnet on port 5005 for error-trapping:$!\n";
$DMPSCRN_IN = *DMPSCRN_IN;
$DMPSCRN_OUT = *DMPSCRN_OUT;
$DMPSCRN_DMP = *DMPSCRN_DMP;

tlnDumpScreen;

sub tlnDumpScreen{
$dmpscreen = new Net::Telnet(
    Timeout=>10,
    Prompt=>'/.+>/',
    Input_log => $DMPSCRN_IN,
    Output_log => $DMPSCRN_OUT,
    Dump_Log => $DMPSCRN_DMP,
    Host => '192.168.6.40',
    Port => '5005'
    );
    $dmpscreen->open();
    $dmpscreen->waitfor('/name:/');
    $dmpscreen->print($user);
    $dmpscreen->waitfor('/password/i');
    $dmpscreen->print($pass);
    $dmpscreen->waitfor('/name:/');
    $dmpscreen->print('getlinglines');
    
    
}

When I run this output, nothing is logged which is what I expect to be done when I run commands from the command terminal (HOSTA:5051). I would appreciate if someone can give me a pointer on how to overcome this problem. Thank you. Thanks p.s, i know the code looks messy. will clean up once i figure out this glitch.
