I am trying to send/receive files with a Unisys system over telnet/SSL via Zmodem. I am well aware that the year is 2007. Before I used expect and Kermit, but now I want this all to be clean inside perl. I handle the telnet/SSL with stunnel and that works great.


My System information:


This his how I handled the Zmodem in the expect script 

#!/usr/local/bin/expect  -f
#!expect  -f $1 $2

set hostid [lrange $argv 1 1]
set retfil [lrange $argv 2 2]

spawn kermit
sleep .4

send -s -- "set protocol zmodem {rz -E} {rz -E} {sz --zmodem --delay-s
+tartup 10 -e -w 2048 %s} {sz -a %s} {rz -E} {rz -E}\r"
send -s -- "telnet $hostid\r"
        -exact  "    Do you want to send a file? Y/\[N\]: " {
                sleep .2
                send -s -- "y\r"
                expect -exact  "    Enter an upload command to your mo
+dem program now."
                sleep 5
                send -s -- "\034\003"
                send -s -- "send $retfil\r"
                send -s -- "c\r"
        }

Here is where I am stuck with perl and all the searching hasn't helped me find a way to send a file via Zmodem. 

#!/usr/bin/perl -w

use strict;
use Expect;


my $exp = Expect->spawn("telnet remoteunisyssystem") or die "Cannot sp
+awn telnet: $!\n";;
   $exp->log_file("testlog");

my $spawn_ok;
my $timeout = 15;

$exp->expect($timeout,
               [
                qr'Do you want to send a file? Y/\[N\]: $',
                sub {
                  my $fh = shift;
                  print $fh "Y\n";
                  exp_continue;
                }
               ],
               [
                'Enter an upload command to your modem program now.',
                sub {
                  my $fh = shift;
                  print $fh "send somefilename\n";
                  exp_continue;
                }
               ],

               [
                eof =>
                sub {
                  if ($spawn_ok) {
                    die "ERROR: premature EOF in login.\n";
                  } else {
                    die "ERROR: could not spawn telnet.\n";
                  }
                }
               ],
               [
                timeout =>
                sub {
                  die "No login.\n";
                }
               ],
               '-re', qr'[#>:] $', #' wait for shell prompt, then exit
+ expect
              );
