set  [node node-id] xot sap sap-name ...

    Modifies the attributes of a XOT SAP entity, which represents the
    point at which the XOT entity gains access to the TCP/IP
    environment for the purposes of listening for inbound XOT
    connections.  The sap-name is a simple name that uniquely
    identifies a particular SAP instance.  The modifiable attributes
    and their data types (in brackets) are:

    local IP address [ip-address]
    local RFC1613 port number [integer]

    By default, XOT's single SAP entity is configured to listen
    on all available IP interfaces (as specified by the local IP
    address 0.0.0.0).  You can create multiple SAP entities, each
    listening on a unique IP address.  However, if you create
    more than one SAP entity, you must assign each entity a
    unique IP address; no SAP entity can use the 0.0.0.0 address.

    In other words, you may do this:

    set xot sap sap-0 -
      local ip address 0.0.0.0

    or this:

    set xot sap sap-0 -
      local ip address 123.23.49.235
    set xot sap sap-1 -
      local ip address 123.23.49.236

    but not this:

    set xot sap sap-0 -
      local ip address 0.0.0.0
    set xot sap sap-1 -
      local ip address 123.23.49.236

    LINK is a subentity of XOT SAP.
