Hello all, I'm tring to write the simplest telnet server that will read characters from the client by the character and not by the word (waiting for "\n"). I've already searched the web and found a module, NetServer::Generic, that will let me build a simple telnet server. I've also found on the web the module, Term::ReadKey, that will let me change the way perl read info from the user, which will be by character. The problem is that they don't work together, any idea? Here is my program: 
#!perl -w

use strict;
use NetServer::Generic;
use Term::ReadKey;

sub Terminal
{
    my ($server) = @_;
    my $input;
    my $key;
    
    while (1) 
    {
        ReadMode(4);
        while (not defined ($key = ReadKey(0))) {};
        ReadMode(0);
        if ($key eq "q")
        {
            return 1;
        }
        else
        {
            print "Got character '" . ord($key) . "'\r\n";
        }
    };
    
    return 0;
}

my $Server = new NetServer::Generic;
$Server->port(23);
$Server->callback(\&Terminal);
$Server->mode("forking");
print "Starting server\n";
$Server->run();

The problem is that the call to "ReadMode(4)" result in error and close of the client: "GetConsoleMode failed, LastError=|6| at C:/Perl/lib/Term/ReadKey.pm line 265" BTW, the script should run on linux and windows. Thanks, Dayan Shay
