Library /sys$common/syshlp/ncphelp.hlb SET, MODULE, X25-SERVER, KNOWN DESTINATIONS, NODE node-id  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Identifies the P.S.I. Access node that is to be the destination
 of the incoming X.25 call.  Specify this parameter if the
 executor node is a VMS node with VAX P.S.I. software in multihost
 mode installed, serving as a connector node.  This parameter is
 mandatory when you specify this destination for first time.  Use
 only with the SET MODULE X25-SERVER or the DEFINE MODULE
 X25-SERVER command.
