Shell Programming and Scripting

Hi all,

Encountered a wierd behaviour which I am unable to understand.

I have a function doing the follow:

function RETRIEVE_PASSWORD
{
if (( $DC_ACCOUNT ))
then
clear
printf "\nEnter Password for ${ConfiguredUser}"
printf "\nPassword: "
stty -echo
read -r DCAcctPwdPart1
fi
}

Problem is that, when I call this function from the main program, it works fine. But when I call it from within another function, it breaks giving me the error:

unable to set stty

It doesn't wait for user input...

Read some information regarding the interactive mode, I planted echo $- in different part of the code, but all returned "h"

What am I missing here. Thanks for any input and opinion.

Regards
Eugene

Forgot to add on, the function was called from a while loop:

cat user.cfg | while read LINE
do
RETRIEVE_PASSWORD
done
