Telnet is probably spitting that out to standard error, which isn't caught by command substitutions and in your code isn't redirected nor piped. Try redirecting telnet's stderr to /dev/null.
If not for this script then for the future, it would likely benefit you to learn more about netcat (aka nc).

xrlogin
XRLOGIN(1) General Commands Manual XRLOGIN(1)NAME
xrlogin - start an xterm that uses ssh (or optionally rlogin or telnet) to connect to a remote host
SYNOPSIS
xrlogin [-l username] [-rlogin|-telnet] [xterm options] remote-host
DESCRIPTION
Xrlogin opens an xterm window and runs ssh, rlogin or telnet to login to a remote host.
Xrlogin automatically passes the -name argument to xterm with a value of "xterm-hostname" where hostname is the name of the remote host.
This allows the user to specify resources in their server's resource manager which are specific to xterms from a given host. For example,
this feature can be used to make all xterm windows to a given remote host be the same color or use a specific font or start up in a spe-
cific place on the screen. Xrsh(1) passes the same string so they are compatible in this regard.
Xrlogin specifies that the default title for the new xterm will be "hostname" where hostname is the name of the remote host. This and the
-name argument above can be overridden with xterm-options on the command line.
One could also use xrlogin's sister command xrsh(1) to open a window to a remote host. In the case of xrsh, the xterm would run on the
remote host and use X as the connection protocol while xrlogin would run the xterm on the local host and use rlogin or telnet as the con-
nection protocol. See xrsh(1) for a discussion of the merits of each scheme.
OPTIONS -l username
When not using -telnet, use username as the id to login to the remote host.
-rlogin
Use the rlogin protocol to open the connection. In general rlogin is preferred because it can be configured to not prompt the user
for a password. Rlogin also automatically propagates window size change signals (SIGWINCH) to the remote host so that applications
running there will learn of a new window size.
-telnet
Use the -telnet protocol to open the connection. Use of telnet provided mostly for hosts that don't support rlogin.
COMMON PROBLEMS
Make sure that the local host is specified in the .rhosts file on the remote host or in the remote hosts /etc/hosts.equiv file. See
rlogin(1) for more information.
EXAMPLES
xrlogin -bg red yoda
Start a local red xterm which connects to the remote host yoda using rlogin.
xrlogin -telnet c70
Open a local xterm which connects to the remote host c70 using telnet.
