Library /sys$common/syshlp/latcp$help.hlb SET, SERVICE, Qualifiers, /CONNECTIONS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /CONNECTIONS
       /NOCONNECTIONS

    Specifies whether a service offered by an OpenVMS system accepts
    incoming connections. If you use the /NOCONNECTIONS qualifier
    to disable incoming connections, users cannot connect to that
    service and receive instead the error message "service is
    disabled".

    By default, a service accepts incoming connections
    (/CONNECTIONS).
