Library /sys$common/syshlp/nclhelp.hlb set, session_control, application, accept mode (Tru64 UNIX)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Default: Immediate     Value: Immediate or deferred

    If accept mode is immediate, then session control will
    automatically accept the connection before activating the
    end user. If accept mode is deferred, then it is up to the
    program to accept or reject the connection.
