/SERVICE_RESPONDER
       /NOSERVICE_RESPONDER

    Specifies whether your system responds to special LAT multicast
    messages that request service information. Some terminal servers
    do not have their own service and node database. When a user on
    such a terminal server requests a connection to a service, the
    server sends a LAT multicast message requesting names of nodes
    that offer the requested service. Service responder nodes reply
    with the requested information.

    If you specify /SERVICE_RESPONDER, your system responds to the
    special LAT multicast messages. (If you specify /NOSERVICE_
    RESPONDER, your system does not respond to those messages.)
    VSI recommends that you set up only one or two nodes in
    the LAN as service responder nodes. The nodes should have the
    largest databases in the LAN. Use this option only if your node
    allows outgoing connections (/CONNECTIONS=OUTGOING_ONLY or
    /CONNECTIONS=BOTH).

    If you do not specify either the /SERVICE_RESPONDER or
    /NOSERVICE_RESPONDER qualifier, the default is that your system
    will not respond to the special LAT multicast messages.
