Telnet of multiple server and ports

Hi,
I do a telnet to a single server using command :telnet tibserver001 9640
The output i get is :
Code:
Trying 10.19....
Connected to tibserver001

However i need to put all the servers in a single file and get the output to see if the server is connected or not.
Code:
#! /bin/bash
telnet tibserver001 9640 > output.log
telnet tibserver004 9642 >>output.log

The above does not seem to work. Is there a better way to script this ?

regards
Sam

telnetrc(4)							   File Formats 						       telnetrc(4)

NAME
telnetrc - file for telnet default options DESCRIPTION
The .telnetrc file contains commands that are executed when a connection is established on a per-host basis. Each line in the file con- tains a host name, one or more spaces or tabs, and a telnet(1) command. The host name, DEFAULT, matches all hosts. Lines beginning with the pound sign (#) are interpreted as comments and therefore ignored. telnet(1) commands are case-insensitive to the contents of the .telnetrc file. The .telnetrc file is retrieved from each user's HOME directory. EXAMPLES
Example 1: A sample file. In the following example, a .telnetrc file executes the telnet(1) command, toggle: weirdhost toggle crmod # Always export $PRINTER DEFAULT environ export PRINTER The lines in this file indicate that the toggle argument crmod, whose default value is "off" (or FALSE), should be enabled when connecting to the system weirdhost. In addition, the value of the environment variable PRINTER should be exported to all systems. In this case, the DEFAULT keyword is used in place of the host name. FILES
