continue perl telnet
I need to telnet to a sun servervia 9023 port.
Normally, I can telnet directly as below:
telnet 10.2.4.9 9023
Trying 10.2.4.9...
Connected to 10.2.4.9.
Escape character is '^]'.
900 Login required.
login username passwd
login username passwd
102 2 records.

I tried to use Net::Telnet with the code following:

#!/usr/bin/perl -w
use Net::Telnet ();
$t = new Net::Telnet (Timeout => 10,Port => 9023,Prompt => '/==> $/');
$t->open("10.2.4.9");
$t->waitfor("900 Login required. $/i");
$t->print("login username passwd");


But it's not successful. This is the error message:

missing opening delimiter of match operator in argument "900 Login required.i" given to Net::Telnet::waitfor() at ./try line 5

How can i fix it ?

NAME

       fence_baytech - I/O Fencing agent for Baytech RPC switches in combination with a Cyclades Terminal Server

SYNOPSIS

       fence_baytech [OPTION]...

DESCRIPTION

       This fencing agent is written for the Baytech RPC27-20nc in combination with a Cyclades terminal server.  The Cyclades TS exports the RPC's
       serial port via a Telnet interface.  Other interfaces, such as SSH, are possible.  However, this script relies  upon  the  assumption  that
       Telnet  is used.  Future features to this agent would allow the agent to work with a multitude of different communication protocols such as
       Telnet, SSH or Kermit.

       The other assumption that is made is that Outlet names do not end in space.  The name "Foo" and "Foo    " are identical when the RPC prints
       them with the status command.

       fence_baytech  accepts  options	on the command line as well as from stdin.  fenced sends parameters through stdin when it execs the agent.
       fence_baytech can be run by itself with command line options which is useful for testing.

       Vendor URL: http://www.baytech.net

OPTIONS

       -a host
	      IP address or hostname to connect to.

       -h     Print out a help message describing available options, then exit.

       -n port

       -p password
	      Password for login.

       -S path
	      Full path to an executable to generate the password for login.

       -q     Quiet mode: print only error messages.

       -V     Print out a version message, then exit.
