HP UFT , unable to get visible text in telnet ssh

my group was using QTP and Reflections for vms to perform screen scrapes to verify online screens on a vms system . with the new hp-uft i am unable to use the getvisibletext function on the window .

QTP command - TelnetText = Window("WRQ Reflection for UNIX").GetVisibleText

which would return the screen of text, the telnet session is under ssh and emulating a vt100 terminal 

under HP-UFT the above command does not return any text , please help me
