Reading password from /dev/tty

hi,
From the below script:

Code:

##########################################pwd_auth.sh########################################################################################
#Author: Pandeeswaran Bhoopathy
#Written on:26th Jan 2012 2:00PM
#This script describes the feature of stty and illustrates the authentication mechanism
#############################################################################################################################################
#!/usr/bin/bash
printf "Enter the password:\n"
stty -echo 
read password </dev/tty
printf "Enter the passwrd again:\n"
read passwrd1</dev/tty
if [ $password = $passwrd1 ]
then
echo "Both the passwords match\n"
else
printf "Passwords do not match\n"
fi
stty echo

is it possible to print the password intermediately in the above script?i.e:is it possible to read the password from /dev/tty?
Similarly, while using

Code:

read -s

,can we retrieve the typed text from where its getting stored . i guess it's /proc/core.but i am unable to retrieve from there.
Please help me.

Thanks

wwsetup

wwsetup(8)						      System Manager's Manual							wwsetup(8)

NAME

       wwsetup, wnn - Sets up the 8-bit option for sendmail and the Wnn character-cell input method for Japanese

SYNOPSIS

       /usr/sbin/wwsetup

DESCRIPTION

       The  wwsetup  script performs one or both of the following tasks: Enables or disables 8-bit transmission code, which is an option supported
       by sendmail software

	      By default, sendmail uses the 7-bit SMTP mail transmission protocol that is the standard for sending mail  over  a  TCP/IP  network.
	      Note  that  enabling the 8-bit option is not generally recommended because it violates the SMTP mail transmission protocol.  Config-
	      ures the Wnn software that supports a character-cell input method that is widely used in Japan

	      If the Tru64 UNIX IOSJPWNNnnn subset is installed, the wwsetup script asks if you want to create the following links if they do  not
	      already exist on the system:

	      /usr/local/bin/Wnn4 --> /usr/i18n/bin/Wnn4 /usr/local/bin/wnn --> /usr/i18n/lib/wnn

	      The script also prompts you to enter the password for Wnn dictionaries if they do not already exist on the system.

	      Both the links and the dictionary password must be in place before Wnn software can be used.

SEE ALSO

       Commands: sendmail(8), jserver(1wnn)

       Note  that the jserver(1wnn) reference page is available only in Japanese and is included in the subset that contains Japanese translations
       of reference pages.

       Others: i18n_intro(5), Japanese(5), l10n_intro(5)
