Telnet issue

In the below script, i want to check telnet port status of list of servers, here where ever port working i am getting output. where ever port is not working (where ever trying) there it's command stuck, there it's needed manual interruption like ctrl+c.
without interception i want run this command and i want to know in which ip telnet is working and where it's not woring
like echo $? {if [ $? -eq 0 ];then echo working;else echo notworking;fi

Code:
for i in `cat conect_ser_05-13-19`;
               do 
                echo ----- $i ---;
                ssh  $i "TERM=vt100;export TERM;echo sleep|telnet unix.com 8089"
              done

RXTELNET(1)						    BSD General Commands Manual 					       RXTELNET(1)

NAME
rxtelnet -- start a telnet and forward X-connections. SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port] DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be able to connect securely to your X server. If port is given, that port will be used instead of the default. If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding. The supported options are: -l Log in on the remote host as user username. -k Disables keep-alives. -t Send telnet_args as arguments to telnet. -x Send xterm_args as arguments to xterm. -X Send kx_args as arguments to kx. -w Use term_emulator instead of xterm. -b Use telnet_program instead of telnet. -n Do not start any terminal emulator. -v Be verbose. EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following. 1. On foo: rxtelnet bar 2. You will get a new window with a telnet to bar. In this window you will be able to start X clients. SEE ALSO
