This setting specifies whether Verastream will support responses for Telnet
Extended connections. The default is Yes. You should not need to change this
setting. If this setting is changed to No, Verastream will inform the host that
is does not support responses when the connection is established. You cannot
change this value while you are connected to a gateway.
The Telnet Extended option is configurable from the Session
Setup or New Model dialog box.
