Escape bash-special character in a bash string

Hi,

I am new in bash scripting. In my work, I provide support to several users and when I connect to their computers I use the same admin and password, so I am trying to create a script that will only ask me for the IP address and then connect to the computer without having me to type the user and password.

Here's the script:
Code:
read -p "Enter ip address: " IP_ADDRESS
pss="123@456"
open vnc://test:$pss@$IP_ADDRESS

If I remove the @ from my password I am able to connect with no issue. I have tried to escape the @ by adding a backslash before the character but still not working (e.g. 123\@456). Do you guys have any suggestions?..

Thanks in advance.

NAME
tsql - utility to test FreeTDS connections and queries SYNOPSIS
tsql { -S servername [-I interface] | -H hostname -p port } -U username [-P password] [-o options] tsql -C DESCRIPTION
tsql is a diagnostic tool provided as part of FreeTDS. It uses the TDS protocol directly to connect to Sybase or Microsoft SQL Servers, and allows the user to issue queries that test the capabilities of FreeTDS. tsql is *not* a replacement for a complete isql, such as sqsh (www.sqsh.org). It is designed to rely on the lowest level FreeTDS library, tdslib, as a way to isolate potential bugs in the protocol implementation. tsql can be run in two ways, one which uses the freetds.conf and one which connects directly using the server's hostname and port. When -S is used, FreeTDS uses the freetds.conf (or equivalent) and environment variables in the normal way to determine the server's ip address and port. You can use -I to specify a filename, overriding FreeTDS's configuration file search algorithm. The -H and -p parameters are provided especially for troubleshooting new configurations (or servers). Use of these parameters causes FreeTDS to ignore any freetds.conf and environment variables. OPTIONS
-S servername the Database Server to which to connect. -I interface a freetds.conf or interfaces file describing servername -H hostname the DNS hostname of the server -p port the port at which SQL Server is listening -U username database login name. If username is not provided, a domain login is attempted for TDS 7+ connections. -P password database password. -L list server "instances" (with -H) -C prints some of the compile-time configuration parameters. -o options apply the options specified to every command. f No footer [result count] h No header [titles] t Print time v Print version q Quiet NOTES
Typing "exit", "quit", or "bye" (or ^D) exits tsql. Typing "version" displays the TDS protocol version. Command batches may be separated with "go" or "GO". If "GO", the version string is reported before executing the batch. After prompting for the password, tsql will attempt to connect to the remote server. tsql displays a counter indicating the number of seconds that it is attempting to connect. Typically, tsql should immediately respond with a '1>' prompt. If you see the counter (1, 2, 3, ...), most likely tsql is unable to connect to the indicated server. If you can connect with "tsql -S servername", your basic FreeTDS installation is working. If you have suggestions for ways to make tsql more useful as a diagnostic tool, please recommend them to the FreeTDS mailing list for con- sideration. HISTORY
tsql first appeared in FreeTDS 0.60. AUTHORS
The tsql utility was written by Brian Bruns. BUGS
Several, to be sure, now that it's documented. :) doc 13 November 2011 tsql(1)
