Use the LOAD VIA command to downline load software to  a  target  node
 via  the  specified circuit.  The target node identification is obtained
 from the volatile database on the executor node.   If the target node is
 on a broadcast circuit, the PHYSICAL ADDRESS parameter must be specified
 in this command.

 LOAD    VIA circuit-id     (parameters ...)

 All underscores found in parameters must be replaced with spaces
 when parameters are used in NCP commands.
