The transfer option specifies the action taken when the user transfers sessions from one physical terminal to another without signing off TPX. If you don't specify a value, TPX will prompt the user for an action.
Possible Values are:
ANY If the terminal type is incompatible, TPX performs the transfer and terminates any sessions that cannot be transferred.
HOLD If the terminal type is incompatible, TPX performs the transfer keeping the incompatible sessions active but inaccessible until the user transfers to a compatible terminal or restarts the sessions.
MULT Disallows all terminal transfers and inactivates the user's sessions on sign off. Use this option if you are allowing multiple users to sign on with a single user ID.
