Problem interfacing with Sage 935AT through terminal server

I am trying to establish an interface with the Sage 935AT using Perl.  I wish to issue commands and capture results using a terminal server connection.  When I telnet into the Sage through the terminal server, the normal interface for the Sage is what a colleague calls "cursive".  In other words, the menu is stagnant, but only one line changes depending on the command given.

Here is my script
     use Net::Telnet;
     use Socket;
     $tn = new Net::Telnet ( Telnetmode => 0);
     $tn->open(Host => $IP,
                Port => 2008);
    # send command "H" to start sage interface
    $tn->print("H");
    # get anything printed out to interface
   @sage = $tn->waitfor('/.+/i');
    print "printing sage\n";
    print $sage[1];

Here is the output that I get.

ahoffmann, thanks for the response.

SAGE INSTRUMENTS 935at

When sending digits:

The line that says "FAR PSQM RESPONDER         &#9575;&#9580;     OFF      o    T" is the only line that changes when the user enters an option (A, B, C, O, o, etc)

At this point, I don't know if this is a problem interfacing with the funky sage interface, and/or I don't know how to properly script Perl using terminal servers

ok, as I assumed: the interface positions the cursor on the screen to change the content
can you figure out which TERM setting your remote box expects?

I didn't mean the serial settings, but the terminal type, for example used in a unix' shell environment variable TERM (like vt100, etc.)

Thanks for you patients

Nothing has happened on this question in more than 8 weeks. It's time for cleanup!

My recommendation, which I will post in the Cleanup topic area, is to
accept answer by ahoffman [grade B] (unresolved but on the right path).

PLEASE DO NOT ACCEPT THIS COMMENT AS AN ANSWER!
