Sometimes there are situations where you may wish to prevent a user from closing the TTWin program or the active session without first cleanly logging off from the host system. This is a setting which is available in TTWin but, in order to prevent an end user (as opposed to an administrator) from modifying such a setting, it is controlled from within TTWin's session configuration or .twc file.
To set TTWin to force a log off from the host before allowing session or program close set the following parameter in the session configuration file (.twc)
AllowDisconnect=0
By default this setting is set to 1. Setting to 0 will prevent a program or session close
whilst a host connection remains active.
Note that this feature requires the host to support a disconnection as opposed to, for example, simply re-displaying a login prompt when a user logs out. Failure of the host system to do so may prevent the user from closing the TTWin program or session.
